Answer 1

Concentration of the \[\ce{C2O^-_{4(aq)}}\] ions in a saturated solution of Ag₂C₂O₄ is 1.1 × 10⁻⁴ mol L⁻¹. Solubility product of Ag₂C₂O₄ is 5.32 × 10⁻¹².

Explanation:

\[\ce{\underset{S}{Ag2C2O4_{(s)}} ⇌ \underset{2S}{2Ag^+_{( aq)}} + \underset{S}{C2O^-_{4(aq)}}}\]

S = 1.1 × 10⁻⁴ mol L⁻¹

K_sp = 4S³ = 4(1.1 × 10⁻⁴)³

K_sp = 5.32 × 10⁻¹²
