Phosphine is not obtained, when:
The reaction of white phosphorous with aqueous NaOH gives phosphine along with another phosphorous containing compound. The reaction is a:
When a small piece of white phosphorous is exposed to air, it reacts with oxygen present in air to form phosphorous oxide. The heat released during the reaction burns the entire phosphorous liberating heat and light.
What will be the balanced equationof the following reaction:-
1) Potassium chlorate on heating decomposes to give pottasium chloride and oxygen gas.
2) The color of pottasium permaganate gets decolourised when added to an acidified solution of ferrous sulphate.
3) Phosphorous reacts with clorine to give phosphorous pentacloride.
4) Sulphur trioxide reacts with water to give sulphuric acid.
If phosphoric acid is allowed to react with sufficient quantity of NaOH, the product obtained is:
