Salt, Water and Carbon dioxide
|
Detailed explanation-1: -Answer: (a) When an acid reacts with metal carbonate, it results in the formation of salt, carbon dioxide, and water. Example: When dilute hydrochloric acid reacts with sodium carbonate, then sodium chloride, carbon dioxide, and water are formed.
Detailed explanation-2: -Acids and metal carbonates 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.
Detailed explanation-3: -We see how metal carbonates and bicarbonates react with acid to form salt, water, and release carbon dioxide.
Detailed explanation-4: -Acids react with metal carbonates or metal bicarbonates to give out carbon dioxide, along with the corresponding metal salts and water. Sodium carbonate reacts with hydrochloric acid to form sodium chloride, carbon dioxide, and water.
