Question

What are the products obtained when magnesium carbonate reacts with HCl?

• A. Magnesium Chloride, hydrogen and carbon dioxide
• B. Magnesium Chloride and hydrogen
• C. Magnesium Chloride, water and carbon dioxide
• D. Magnesium Chloride and carbon dioxide

Answer 1

The correct option is C Magnesium Chloride, water and carbon dioxide

The reaction of any carbonates with HCl results in salt, hydrogen and evolution of some $C{O}_2$ gas.
Here, magnesium carbonate reacts with HCl to give magnesium chloride($MgC{l}_2$. The overall reaction is as follows:
$MgC{O}_3+HCl\to MgC{l}_2+H_{2}O+C{O}_2$
