Ammonium hydroxide on warming decomposes to form ammonia gas and water.
When an ammonium salt is warmed with sodium hydroxide solution, ammonia gas is evolved. State three ways in which you could identify this gas.
Write a balanced chemical equation for each of the following :
1. Carbon disulphide burns in air to give carbon dioxide and sulphur dioxide.
2. Calcium hydride reacts with water to form calcium hydroxide and hydrogen gas.
3. Methyl alcohol burns in air to form carbon dioxide and water.
4. Liquid hydrogen peroxide decomposes to give water and oxygen gas.
5. Aluminium hydroxide reacts with sulphuric acid to give ammonium sulphate and water.
6. Aluminium sulphate solution reacts with sodium hydroxide to form a precipitate of aluminium hydroxide.
If ammonia gas is mixed with water then will it react with water to form ammoniun hydroxide?
(a) What is the action of red litmus on (i) dry ammonia gas (ii) solution of ammonia gas in water? (b) State the observations you would make on adding ammonium hydroxide to aqueous solution of (i) Ferrous sulphate (ii) Aluminium chloride. [3 MARKS]
