Write the balanced equation.
1. Calcium carbonate reacts with dil. Hydrochloric acid
Action of conc. Sulphuric acid as a least volatile acid
Reaction of dil. Nitric acid with sodium carbonate.
IV. Zinc is heated with sodium hydroxide solution.
Sodium sulphite reacts with dil. Sulphuric
Answers
Answer:
(1).When calcium carbonate reacts with hydrochloric acid, carbon dioxide gas is produced. 1. When calcium carbonate reacts with hydrochloric acid, carbon dioxide gas is produced. ... As carbon dioxide escapes from the flask it loses mass.
Sulphuric acid is less volatile acid in comparison to nitric acid and hydrochloric acid or you can say it is non volatile acid with higher boiling point. Sulphuric acid displaces the volatile acid from its salt as:
NaCl+H2SO4→<200∘CNaHSO4+HCl
Nitric acid reacts with sodium carbonate to form sodium nitrate, carbon dioxide and water. 2HNO3+Na2CO3→2NaNO3+CO2+H2O. Sulfuric acid reacts with calcium carbonate to form calcium sulfate, carbon dioxide and water.
When sodium hydroxide solution is heated with zinc granules then Sodium zincate and hydrogen gas are formed. The salt formed by the reaction between a base and a metal, the metal is present as a part of the Negative Ion . All the metals do not react with bases to form salt and hydrogen gas.
Sodium sulfite react with sulfuric acid to produce sodium bisulfate, sulfur dioxide and water.
