Product description
2. Give examples of the use of precipitation reactions in qualitative and quantitative analysis (reaction equation, conditions for their implementation). Suggest ways to shift the heterogeneous equilibrium to the side:
A) lowering the solubility of the precipitate
B) sediment dissolution
In the formation of which poorly soluble compound, the solubility of the precipitate is minimal? Support your answer with calculations.
Ks(AgI)=8.3*10-17
Ks(Ag2SO4)=1.6*10-5
Ks(Ag3PO4)=1.3*10-20
