`Ca(OH)_(2)`

`Na_(2)CO_(3)`

`NaOCI`

Text Solution

Verified by Experts

The correct Answer is:

A, C, D

b. Clarke's method: `underset("Temporary hardness")Ca(HCO_(3))_(2) +Ca(OH)_(2)rarr2CaO_(3)darr2H_(2)O`
c. `Ca(HCO_(3))_(2)+Na_(2)CO_(3)rarr CaCO_(3)darr 2NAHCO_(3)`
d. `NaOHI+H_(2)O`

`HOCI+NaOH`
`O^(Theta)H+HCO_(3)^(Theta)rarr CO_(3)^(2-)+H_(2)O`
