What you will learn

Ksp(BaSO4) = 1.1 x 10^-10 mol^2/dm^6; mix 25.0 cm^3 of 0.010 mol/dm^3 BaCl2 with 25.0 cm^3 of 0.020 mol/dm^3 Na2SO4.
Volume doubles on mixing, so concentrations halve: [Ba2+] = 0.0050 mol/dm^3 and [SO4 2-] = 0.010 mol/dm^3.
Ionic product Q = (0.0050)(0.010) = 5.0 x 10^-5 mol^2/dm^6, which is much greater than Ksp.

Keep the same topic and move to the explanation or a quick check.
