Question

If equal volumes of B a C l 2 and NaF solutions are mixed, which of these combinations will not give a precipitate? Substance K s p B a F 2 1.7 × 1 0 - 7, 0.004 M B a C l 2 and 0.02 M NaF, 0.010 M B a C l 2 and 0.015 M NaF, 0.015 M B a C l 2 and 0.010 M NaF, 0.020 M B a C l 2 and 0.002 M NaF

MARKS App · Accepted Answer

In the mixture of 0.02 M B a C l 2 and 0.002 M NaF, the ionic product is less than solubility product, hence there will be no precipitate of B a F 2 .
