Question

how do metal carbonates and metal carbonates react with acid taking magnesium as metal write balanced chemical equation in both cases state the method to test gas evolved in reaction



​

Answer 1

Metal carbonates and Metal Hydrogencarbonates reacts with acids and produces corresponding metal salt, carbon dioxide and water. ... Both the reaction produces CO2 which on passing through lime water makes lime water milky due to formation of calcium carbonate. On passing excess carbon dioxide following reaction occurs.

Answer 2

Answer:

When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made. The carbon dioxide causes bubbling during the reaction, which is observed as fizzing.
