Question

At 25°C, the solubility product constant (Ksp) for silver chromate, Ag2 CrO4, is 1.1 x 10-12. What is the concentration of Ag+ ions in a saturated solution? 1.3 x 10M 3.3 x 10-5M 1.0 x 10 M 6.5 x 10-SM 2.1x 10 M

Answer 1

solubiliy means the maximum amount of solute dissolved in a solvent at equilibrium. And The resulting solution is called a saturated solution. So maximum amount of Ag+ ion soluble in solution is 1.3×10^-4 M Or 1.3×10^-4 mol/L
