# What are the products when lithium ion and iodide are combined?

Jan 22, 2017

$\text{Lithium iodide}$

#### Explanation:

We can represent this by the ionic equation (the which must conserve mass and charge):

$L {i}^{+} + {I}^{-} \rightarrow L i I \left(s\right)$

What do I mean by conservation of mass and charge?

In aqueous solution, lithium iodide would exist as aquated $L {i}^{+} \left(a q\right)$ and ${I}^{-} \left(a q\right)$ ions. We could precipitate the ionic species if we made the solution a little bit less polar, i.e. by adding ethyl alcohol.
