Write a balanced equation for the action of warm water on magnesium nitride.
In the preparation of nitric acid from KNO3 concentrated sulphuric acid is used in place of hydrochloric acid. Why?
Give reasons for the following:
In the laboratory preparation of nitric acid, the mixture of concentrated sulphuric acid and sodium nitrate should not be heated very strongly above 200°C.
Nitric acid cannot be concentrated beyond 68% by the distillation of a dilute solution of HNO3. State the reason.
Identify the substance underlined:
The dilute acid which is an oxidizing agent.
Write the balanced equation for the following:
Action of concentrated nitric acid on copper.
Write the balanced equation for the following:
Action of heat on AgNO3
Write sqauential observation for effect of heat on Copper nitrate.
From the formulae listed below, Choose, one, corresponding to the salt having the given description:
AgCl, CuCO3, CuSO4.5H2O, KNO3, NaCl, NaHSO4, Pb(NO3)2, ZnCO3, ZnSO4, 7H2O.
