The molar solubility of Cd (OH)(2) " is ...

The molar solubility of `Cd (OH)_(2) " is " 1.84 xx 10^(-5) M`. Calculate the expected solubility of `Cd(OH)_(2)`in a buffer solution of pH = 12.

Text Solution

Verified by Experts

`Cd (OH)_(2) hArr underset(S)(Cd_((aq))^(2+)) + underset(10^(-2))( 2OH_((aq))^(-) )`
`2.49 xx 10^(-14) = S(10^(-2))^(2) " " :. S = 2.49 xx 10^(10M) `
