Equal volumes of `0.02M CaC1_(2)` and `0.0004M Na_(2)SO_(4)` are mixed. Will a precipitate from? `K_(sp)` for `CaSO_(4) = 2.4 xx 10^(-5)`?

Explanation

`{:(,CaC1_(2)+,Na_(2)SO_(4)rarr,CaSO_(4)+,2NaC1),("Mili moles",0.02V,0.004V,0,0),("Suppose V ml of both are mixed",,,,):}`
`:. [Ca^(2+)] = (0.02V)/(2V) = 10^(-2)M`,
`[SO_(4)^(2-)] = (0.004V)/(2V) = 2 xx 10^(-4)M`
Thus, `[Ca^(2+)] [SO_(4)^(2-)]` in solution `lt K_(sp)`
`2 xx 10^(-6) lt 2.4 x 10^(-5)`
`:. CaSO_(4)` will not precipitate
