# How do we prepare a solution of potassium iodide in water?

Jul 4, 2017

You want to make a solution of $\text{potassium iodide....}$?

#### Explanation:

$K I$ is quite soluble in water, to the tune of $140 \cdot g$ of salt per $100 \cdot m L$ of water........

So pours your water onto the salt, and let it rip......

The addition of potassium iodide to a water slurry of iodine can bring the iodine up into solution as $K {I}_{3}$,

${I}^{-} + {I}_{2} \left(s\right) \stackrel{{H}_{2} O}{\rightarrow} {I}_{3}^{-}$
