Q1
(a) Write a balanced chemical equation for the laboratory preparation of nitric acid.
(b) In the preparation of nitric acid from KNO3, concentrated hydrochloric acid is not used in place of concentrated sulphuric acid. Explain why ?
(c) Conc. nitric acid prepared in laboratory is yellow in colour. Why ? How is this colour removed ?
(d) 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 200oC.
