Question:
What are the products of the reaction when carbonate reacts with an acid?
ASalt + Water
BSalt + Water + Carbon dioxide
CCarbon dioxide
DSalt+Hydrogen
Answer:
B. Salt + Water + Carbon dioxide
Explanation:
When acid reacts with carbonates:
When an acid reacts with a carbonate, it produces salt, water, and carbon dioxide gas.
The reaction is exothermic, that is it releases heat energy.
The carbon dioxide gas causes bubbling during the reaction, which is observed as fizzing.
Eg: 2HCl + Na2CO3 → 2NaCl + H2O + CO2
