The solubility product for a salt of the type $AB$ is $4 \times 10^{-8}$. What is the molarity of its standard solution?

A

$4 \times 10^{-4} \;mol / L$

B

$2 \times 10^{-4} \;mol / L$

C

$16 \times 10^{-16} \;mol / L$

D

$2 \times 10^{-16} \;mol / L$

Solution

For salt AB

$K_{ ap }=( s )^{2} \Rightarrow s =\sqrt{ K _{ sp }}$

$s =\sqrt{4 \times 10^{-8}}=2 \times 10^{-4} M$
