Question

At 30&deg;C the solubility of Ag2CO3 (Ksp = 8 &times; 10&ndash;12) would be greatest in one litre of:a)0.05M Na2CO3b)0.05M AgNO3c)Pure waterd)0.05 M K2CO3Correct answer is option 'C'. Can you explain this answer?

Answer

In opt a,b&d there is common ion carbonate so its dissociation decreases so solubility decreases ..There is no common ion in water hence it has greater solubility .

Answer

Solubility for any compound is greater if it make complex after reaction, after it solubility of every compound is greater in water, and after it u can find solubility by : S @ 1/Concantration
@= proportional
