The molar solubility of

Cd\,{\left( {OH} \right)_2}

1.84 \times {10^{ - 5}}\,m

in water. The expected solubility of

Cd\,{\left( {OH} \right)_2}

in a buffer solution of

pH = 12

View answer and explanation

Correct option: D

2.49 \times {10^{ - 10}}\,M\,

Option D (

2.49 \times {10^{ - 10}}\,M\,

) is correct because it calculates the solubility of Cd(OH)2 in a buffer solution at pH 12 by considering the hydroxide ion concentration and the solubility product.
