What is the concentration of ca2+(aq) in a saturated solution of caco3? (note: the solubility product constant ksp for caco3 is 4.9 × 10–9.)

7×10⁻⁵ M

Explanation:

Consider the ICE take for the solubility of the solid, CaCO₃ as:

                                 CaCO₃    ⇄     Ca²⁺ +    CO₃²⁻

At t =equilibrium                                s             s            

The expression for Solubility product for CaCO₃ is:

Given

So, Ksp is:

s = 7×10⁻⁵ M

The concentration of Ca²⁺ is 7×10⁻⁵ M

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
