The concentration of ag + in a solution saturated with ag2c2o4 (s) is 1.7 * 10-4 m. calculate ksp for ag2c2o4.

Silver oxalate dissociation equation is following:

Ag ₂C₂O₄ (s) ⇄ 2Ag⁺ (aq) + C₂O₄²⁻ (aq)

According to reaction follows next stoichiometric ratio:

[Ag⁺] : [C₂O₄²⁻] = 2 : 1

[C₂O₄²⁻] = [Ag⁺] / 2

[C₂O₄²⁻] = (1.7*10⁻⁴) / 2 = 8.5*10⁻⁵ M

So, solubility product constants for silver oxalate is:

Ksp = [Ag⁺]² x [C₂O₄²⁻]

Ksp = [1.7*10⁻⁴]² x [8.5*10⁻⁵]

Ksp = 2.46*10⁻¹²
