Some of the oceans on this list are still completely hypothetical, but the evidence says they’re all physically possible – which means that in an infinite universe, somewhere there must be an ocean of liquid ammonia washing up on an icy shore. Pack your bags and prepare to set sail on some of the strangest alien seas in the universe.Water, Water EverywhereOn Gliese 1214b, 47 light years away in the constellation Ophiuchus, the ocean is technically made of water, but it’s still one of the last places in the universe you’d want to go for a swim. There’s probably no liquid water anywhere on the planet, according to a 2010 paper. Instead, under extreme heat and pressure, the water here takes on bizarre forms.The upper layers of the atmosphere look normal enough: familiar clouds of water vapor, heated to about 540⁰F (280 C) thanks to Gliese 1214b’s proximity to its red dwarf star. As you dive further down into the planet’s watery envelope, though, the heat and pressure build up to such extremes that water starts behaving in some very weird ways. When you heat a substance under very high pressure, it passes what’s called its supercritical point – the point at which the distinction between liquid and gas breaks down, and the material becomes a supercritical fluid, with some properties of both liquid and gas; it’s neither and both all at once. Supercritical water, produced under lab conditions, has industrial uses here on Earth, but there may be a globe-spanning ocean of it beneath the clouds of Gliese 1214b, under at least 218 times as much pressure as we feel on Earth’s surface. Venture even deeper on Gliese 1214b, and you’ll find water in the form of an ionized gas called a plasma. A plasma forms when a gas gets energized enough to knock some electrons off its atoms. That gives the substance a positive charge. The result is an extremely hot, ionized material that’s neither a liquid nor a gas, but it behaves a bit like both. It’s also denser than supercritical water, and it’s very electrically conductive.Most of the gas in our Sun and other stars is actually plasma, but the Sun’s hydrogen plasma is super-hot, over 9,940⁰F (5500 C). The deep ocean of plasma water on Gliese 1214b is relatively cool by comparison at just 6,700⁰F (3700 C).How does a planet get this watery and weird? When

We stand with Ukraine. 🇺🇦 * The SI units is the recommended method of reporting clinical laboratory results Units of measurement µmol/L, µg/dL, µg/100mL, µg%, µg/mL, µg/L, mg/L Ammonia, derived from the catabolism of amino acids and from the action of intestinal bacteria on dietary protein, is converted to urea in the liver hepatocytes and so rendered nontoxic. Under normal circumstances the concentration of ammonia in the circulation remains low, typically less than 50 μmol/L (85 μg/dL). Studies have shown that excess ammonia can have a toxic effect on the central nervous system and clinical manifestations are typically neurological disturbances. Elevated levels of ammonia may be either due to: (i) Inborn errors of metabolism; or (ii) Secondary to other conditions. Inborn errors of metabolism are the major cause of elevated ammonia in infants and usually the result of urea cycle enzyme deficiencies. Inherited disorders affecting the metabolism of the dibasic amino acids (lysine and ornithine) and those involving the metabolism of organic acids may also produce elevated levels of circulating ammonia. Elevated ammonia may also be observed in severe liver failure as may occur in Reye’s Syndrome, viral hepatitis or cirrhosis.

Producer than both Germany and Israel. These investments are all backed by China. China is also taking more product from this part of the world, where it feels it has a great degree of control over pricing. But China is also looking further afield, at potash investments in Thailand, Republic of Congo and even in Spain. CRU now has around 9 Mt of Chinese-backed potash investments in our ‘probable-case’ forecast, with a large chunk of that likely to enter our ‘base-case’ forecast pressuring prices in future.Blue ammonia to continue advancing while green ammonia falters (outside China): There are many different cost estimates for green ammonia which CRU thinks are too low. There are a number of different green ammonia products on the drawing board which we do not think will advance. They will need significant supply-side subsidies. We do not think the price of blue or green ammonia will be high enough to incentivise many of these planned projects to operate in a free market. More clarity is needed over demand-side incentives in places such as Japan and South Korea. Blue ammonia has more potential than green and because it has a lower carbon footprint than grey ammonia is advantageous for sending product into Europe as CBAM is implemented in 2026. Greenfield blue ammonia projects will come into production over the coming years in the US and Qatar along with some brownfield retrofit operations using CCS in the US. The project pipeline supports our call that blue ammonia will be the focus of investments for the next few years. Green ammonia development will most likely focus on China. Want to read more?

Fish waste, and decaying organic mater like fish food, is a common source of ammonia, although it is not recommended to start adding fish before your cycle is complete. Fish can quickly produce more ammonia than your new tank can handle, and a sudden ammonia spike can spell disaster for your animals.Instead let your tank run with a live rock for a week or more and then add in a couple invertebrates, like hermit crabs, crabs, and shrimp. This bunch of critters is also called the clean up crew. Feed your invertebrates a very small pinch of food each day and the waste they produce will create ammonia. Test Test TestDuring the cycle process, you want to start testing your aquarium almost every day for ammonia, nitrites and nitrates. This will help you understand if the cycle is underway and when it is safe to start adding livestock. After a week or ten days, you should see a spike in ammonia concentration, jumping from zero to a higher number. This is followed by a spike in nitrite, follow by a spike in nitrate. After your nitrate goes up, your nitrite and ammonia level should fall back down to zero. Once you have observed this change in water chemistry your Nitrogen cycle is complete.What Going OnThe cycle starts with ammonia, but the goal is to establish a colony of nitrobacter bacteria which process nitrite into less harmful nitrate. How it works is nitrosoma bacteria start converting ammonia, to nitrite. Then nitrobacter bacteria being consuming the harmful nitrite into less harmful nitrate.Nitrate levels should be in trace amounts in the aquarium, and a safe range for a reef tank is below 5ppm. If you have a fish only reef tank you can have your levels higher up to 40ppm, however, it is always recommended to have level lower than 5ppm. That being said, certain soft corals and especially giant clams appreciate a little

How to calculate your Un-ionized ammonia levels

Testing for HalidesSilver ions & ammoniaHalide ions can be identified in an unknown solution by dissolving the solution in nitric acid and then adding silver nitrate solution dropwiseThe nitric acid is to prevent any false positive results from carbonate ions precipitating out with silver ionsThe halide ions will react with the silver nitrate solution as follows:Ag+ (aq) + X- (aq) → AgX (s)(ionic equation)Where X- is the halide ionThe state symbols are key in this equationIf the unknown solution contains halide ions, a precipitate of the silver halide will be formed (AgX)A silver halide precipitate is formed upon addition of silver nitrate solution to halide ion solutionSilver chloride (AgCl) is a white precipitateSilver bromide (AgBr) is a cream precipitateSilver iodide (AgI) is a yellow precipitateThe silver halide precipitates are dense and characteristically colouredAdding ammoniaBecause the white, cream and yellow precipitates could look very similar in colour, ammonia is often used as a follow up test to determine which halide ion is presentDilute followed by concentrated ammonia is added to the silver halide solution to identify the halide ionIf the precipitate dissolves in dilute ammonia the unknown halide is chlorideIf the precipitate does not dissolve in dilute, but does dissolve in concentrated ammonia the unknown halide is bromideIf the precipitate does not dissolve in dilute or concentrated ammonia, then the unknown halide is iodideSilver chloride and silver bromide precipitates dissolve on addition of ammonia solution whereas silver iodide is insoluble in ammoniaReaction of Halide Ions with Silver Nitrate & Ammonia SolutionsConcentrated sulfuric acidChloride, bromide and iodide ions react with concentrated sulfuric acid to produce toxic gasesThese reactions should therefore be carried out in a fume cupboardThe general reaction of the halide ions with concentrated sulfuric acid is:H2SO4(l) + X-(aq) → HX(g) + HSO4-(aq)(general equation)where X is the halide ionReaction of chloride.
