When acid reacts with metal carbonate, _______ is/are formed.
-
A.
Water
-
B.
Carbon dioxide
-
C.
Salt
-
D.
All of the options
Correct Answer:
D. All of the options
Explanation:
When an acid reacts with a metal carbonate, the chemical reaction consistently produces three products: a salt, water, and carbon dioxide gas. The salt's identity depends on the specific metal in the carbonate and the type of acid used. For example, reacting calcium carbonate with hydrochloric acid yields calcium chloride (the salt), along with water and carbon dioxide. This process is often identified in a laboratory by the visible fizzing or effervescence caused by the release of carbon dioxide. Therefore, since all three substances are generated during the reaction, the correct choice is that all the listed options are formed.
