Text Solution

Verified by Experts

The correct Answer is:
B
Clark's process is a commercial method of water softening .
A calculated amount of quick is added to hard water , bicarbonates are converted into insoluable calcium and magnisium carbonates which are filled off .
`CaO +H_(2)O to Ca(OH)_(2)`
`Ca(HCO_(3))_(2) +Ca(OH)_(2) to 2CaCO_(3) uarr +2H_(2)O `
