Question

$MgO$ when mixed with a saturated solution of $MgC{l}_2$ sets to a hard mass known as 'sorel cement'. The composition of sorel cement is $MgC{l}_2.nMgO.x{H}_{2}O$. The value of $n$ is:

• A. 2
• B. 5
• C. 3
• D. 1

Answer 1

The correct option is C 3

There are two types of sorel cement 3 phase and 5 phase.

$MgC{l}_2.3Mg(OH{)}_2.8H_{2}O$ is 3 phase sorel cement.
