Question

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

Answer 1

`"Lithium iodide"`

Explanation:

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

`Li^(+) + I^(-) rarr LiI(s)`

What do I mean by conservation of mass and charge?

In aqueous solution, lithium iodide would exist as aquated `Li^(+)(aq)` and `I^(-)(aq)` ions. We could precipitate the ionic species if we made the solution a little bit less polar, i.e. by adding ethyl alcohol.
