Question

In a saturated aqueous solution of ag2co3, the silver ion concentration is 0.000253 m and the carbonate ion concentration is 0.000127 m. calculate the solubility product, ksp, for ag2co3.

Answer 1

Ag2Co3 ->2Ag(+) +CO3(2-)

Ksp=(Ag)^2 (Co3(2-)

Concentration of Ag=0.000253m

Concentration of CO3(2-)=0.000127m

Ksp=(0.000253)^2*0.000127

=8.12*e^-12
