Question

Name the compound A in the given experiment which produce CO2 V reacts with sulphuric acid. H.SO. Carbon dioxide Ar Lime water Α. metal oxide B. metal carbonate C. mental hydrogen carbonate D. both (B) and (C)​

Answer 1

Answer:

both b and c i think

Answer 2

In the experiment, metal carbonate and metal hydrogen carbonate react with sulphuric acid to form carbon dioxide. (OPTION D) as options b and c are correct.

Explanation

CHEMICAL REACTIVITY OF METAL CARBONATES -

• Metal carbonates and metal hydrogen carbonates are basic and soluble in water.
• They do not show chemical reactions with base.
• On addition of acid to metal carbonates, salt is formed as a result of a neutralization reaction.
• The byproducts in the reaction are carbon dioxide gas and water vapors.
• The reaction is -

                        Metal carbonate + acid → salt + water + carbon dioxide.

• The carbon dioxide is evolved with bubbles and frizzing sounds and turns lime water milky.
