Assuming that "mM" means "millimolar", the solution specified contains 6 millimoles of ammonium sulphate per liter. Therefore, 25 ml of the solution contains 6(25/1000) = 0.15 millimoles. By definition, there are 1000 micromoles per millimole. Therefore, 0.15 millimoles = 150 micromoles.
What else can I help you with?
How many ions are present in ammonium sulphate?
Ammonium sulphate consists of two ions: ammonium (NH4+) and sulphate (SO4^2-).
What percentage of nitrogen present in ammonium sulphate?
20.5 % ~ 21 %
What is the ammonium ion present in?
Ammonium ion (NH4+) is present in all ammonium salts (eg. ammonium chloride, or ammonium nitrate), and in smaller amounts in an ammonia (NH3) solution.
How could test for the ammonium ion?
Bases displace ammonia from ammonium compounds, so... 1) Take small amount of the substance that you want to test to see if ammonium ions are present 2) Add some sodium hydroxide 3) Heat gently 4) Ammonia gas is produced if the ammonium ion was present. You can know that ammonia gas is given off if the gas turns damp litmus paper blue.
Is Ammonium Sulfite in fertilizer?
No. Ammonium Sulphate may be present in some fertilisers, but not sulphite.
Please help me I need to know what these are made up of!(NH_(4))_(2)SO_(4)?
This is the chemical salt 'Ammonium sulphate'. It is usually written as ' (NH4)2SO4 The (NH4)2 moiety tells us that there are '2'(two) ammoniums present. Since ammonium is made up of NH4 , then there are two(2) nitrogen (N) present and there are eight(8 = 4 x 2) hydrogen(H) present. The SO4 moiety tells us that there is one(1) sulphur (S) and there are four(4) oxygen present. Unlike the ammonium moiety there is no doubling of the sulphate moiety. Ammonium sulphate is a agricultural fertiliser.
Is ammonia a metallic hydride?
No, ammonia is commonly called NH4OH, or ammonium hydroxide. However in actual fact it is a NH3 + H2O solution. There is no metal (or metal ion) present.

What base does household ammonia contain?
Household ammonia typically contains ammonia dissolved in water, which is commonly referred to as ammonium hydroxide. The ammonia is present in aqueous form, with a concentration typically ranging from 5-10%.
Why do we saturate ammonium sulphate in rothera's test?
In Rothera's test, ammonium sulfate is saturated to provide a concentrated solution that aids in the separation of ketones and aldehydes from other compounds in a mixture. Saturating the solution ensures that the test is specific to detecting the presence of ketones and aldehydes, as these compounds have a higher solubility in the saturated ammonium sulfate solution compared to other substances. This selective solubility allows for the accurate identification of the target compounds in the test sample.
Kjeldahl method for estimation of nitrogen in inorganic organic compound?
This is a very convenient method but its use is restricted.This method is suitable for estimating nitrogen in those organic compounds in which nitrogen is linked to carbon and hydrogen. The method is not used in the case of nitro, azo and azoxy compounds. The method is extensively used for estimated nitrogen in food, fertilizers and agricultural products.Principle:- the method is based on the fact that when the nitrogenous compound is heated with concentrated sulphuric acid in presence of copper sulphate, the nitrogen present in the compound is quantitatively converted to ammonium sulphate. The ammonium sulphate so formed is decomposed with excess of alkali and the ammonia evolved is estimated volumetrically. The percentage of nitrogen is then calculated from the amount of ammonia.
What happens when NH3 is dissolved in water?
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium:NH3 + H2O ------- > NH4+ + OH-Ammonia takes it name from the worshippers of the Egyptian god Amun - the Ammonians, because they used ammonium chloride (NH4Cl) in their rites.
