When temporary hard water containing `Mg(HCO_(3))_(2)` is boiled, the ppt. formed is of

A

`MgCO_(3)`

B

MgO

C

`Mg(OH)_(2)`

D

None of these.

Text Solution

Verified by Experts

The correct Answer is:
C
`Mg(OH)_(2)` is less soluble than `MgCO_(3)`. On boiling temporary hard water containing `Mg^(2+)` ions, the ppt. obtained is of `Mg(OH)_(2)` are not that of `MgCO_(3)`.
