0.03 mole of Ca^(2+) ions is added to a litre of 0.01 M SO_(4)^(2-) solution. Will it cause precipitation of CaSO_(4) ?K_(sp) "for" CaSO_(4)=2.4xx10^(-5).

0.03 mole of Ca^(2+) ions is added to a litre of 0.01 M SO_(4)^(2-) so

1.	0.03 mole of Ca^(2+) ions is added to a litre of 0.01 M SO_(4)^(2-) solution. Will it cause precipitation of CaSO_(4) ?K_(sp) "for" CaSO_(4)=2.4xx10^(-5).
Answer» Solution :In the final solution, `[Ca^(2+)]=0.03 M and [SO_(4)^(2-)]=0.01 M`. Hence, ionic PRODUCT of `CaSO_(4) = (0.03) (0.01)=3xx10^(-4)` which is greater than `K_(SP)`. Hence, precipitation will OCCUR.
