The product of the concentration of the ions of an electrolyte raised to power of their coefficients in the balanced chemical equation in the solution at any concentration . Its value is not constant and varies with change in concentration . Its value is not constant and varies with change in concentration . Its value is not constant and varies with change in concentration . Ionic product of the saturated solution is called solubility product K_(sp) (i) When K_(ip) = K_(sp) , the solution is just saturated and no precipitation takes place . (ii) When K_(ip) lt K_(sp) the solution is unsaturated and precipitation will not take place . (iii) When K_(ip) gt K_(sP) the solution is supersaturated and precipitation takes place . The solubility product K_(sp) , of sparingly soluable salt MX at 25^(@) is 2.5 xx10^(-9) . The solubility of the salt in mol L^(-1) at this temperature is :
