The `K_(a)` value of `CaCO_(3)` and `CaC_(2)O_(4)` in water are `4.7 xx 10^(-9)` and `1.3 xx 10^(-9)`, respectively, at `25^(@)C`. If a miaxture of two is washed with `H_(2)O`, what is `Ca^(2+)` ion concentration in water?

The K_(sp) value of CaCO_(3) and CaC_(2)O_(4) in water are 4.7 xx 10^(-9) and 1.3 xx 10^(-9) , respectively, at 25^(@)C . If a mixture of two is washed with H_(2)O , what is Ca^(2+) ion concentration in water?

The values of K_(sp) of CaCO_(3) and CaC_(2)O_(4) are 4.7 times 10^(-9) and 1.3 times 10^(-9)M^(2) respectively at 298 K. If a solid mixture of these two salts is extracted with water, what is the concentration of Ca^(2+) ions in the aq. extract?

CaCO_(3) and BaCO_(3) have solubility product values 1 xx 10^(-8) and 5 xx 10^(-9) , respectively. If water is shaken up with both solids till equilibrium is reached, the concentration of CO_(3)^(2-) ion is
