I have the following doubts while understanding the concept. Please help me solve them :-
(1) What is a precipitate exactly? While determining the Ksp values, we say that there in a dynamic equilibrium between the solid undissolved solute in contact with the solution and the ions in solution. Is this solid undissolved solute the 'precipitate'?
(2) Is there any difference between such solutions and a saturated solution?? If yes, then what? And if not, does this mean that saturated solutions contain precipitate?
(3) We say that when ionic product > Ksp, the equilibrium is disturbed and the reaction proceeds in the backward direction and precipitation occurs. But isn't there a precipitate (undissolved solid solute) at the above equilibrium? Then why this 'other' precipitation?
