# How do you make saturated solution of potassium iodide?

Mar 4, 2018

Can you define saturation....?

#### Explanation:

$K I \left(s\right) \stackrel{{H}_{2} O}{r} i g h t \le f t h a r p \infty n s {K}^{+} + {I}^{-}$..

...and this describes an equilibrium scenario, where the concentration of $K I \left(a q\right)$ 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. $1 - 2 \cdot m L$, and load the solution with $2 - 3 \cdot g$ 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..$\text{I could go a cold one son!}$).
