Name a metallic nitrate that is not to be used for the preparation of nitric acid in lab.
Reactions:
Therefore, Sodium Nitrate(NaNO3) is not used for the preparation of nitric acid in the laboratory.
(a) (i) Explain, why only all glass apparatus should be used for the preparation of nitric acid by heating concentrated acid and potassium nitrate. (ii) Write a chemical equation to illustrate the acidic nature of nitric acid. (iii) Name the products formed when ammonium nitrate is heated.
Explain why
(a) Only all-glass apparatus should be used for the preparation of nitric acid by heating concentrated sulphuric acid and potassium nitrate.
(b) Nitric acid is kept in a reagent bottle for a long time.
Nitric acid is not used for the preparation of hydrogen from metals. why?
