Can you define saturation....?

Explanation:

#KI(s) stackrel(H_2O)rightleftharpoonsK^+ +I^-#..

...and this describes an equilibrium scenario, where the concentration of #KI(aq)# is the SAME as it would be were the solution were in equilibrium with UNDISSOLVED solute.

This site reports exceptionally high solubility... And so to make the stuff, take a SMALL volume of water...approx. #1-2*mL#, and load the solution with #2-3*g# of the potassium salt.

AS always, saturation, depends on temperature in that a hot solvent can solvate more solute than a cold one...(and that sounds like an Australian beer commercial..#"I could go a cold one son!"#).
