Question

Fill in the blank :
$MgO+HCl\to$__________

• A. $MgC{l}_2+H_{2}O$
• B. $Mg(OH{)}_2+H_{2}O+C{l}_2$
• C. No reaction
• D. None of these

Answer 1

The correct option is A

$MgC{l}_2+H_{2}O$

$MgO$ is basic in nature and $HCl$ is an acid. They both react and undergo a neutralisation reaction resulting in the formation of a salt ($MgC{l}_2$) and water.

$MgO+2HCl\to MgC{l}_2+H_{2}O$
