Question

How do you write out the formula, complete ionic, and net ionic reaction for a reaction occurring when lead(IV) nitrate reacts with barium chromate?

Answer 1

`2BaCrO_4(aq) + Pb(NO_3)_4(aq) rarr Pb(CrO_4)_2(s)darr + 2Ba(NO_3)_2(aq)`

Explanation:

I have an idea that barium chromate is pretty insoluble stuff. Nevertheless, lead(IV)chromate is probably even more insoluble.

The net ionic equation is:

`Pb^(4+) + 2CrO_4^(2-)rarr Pb(CrO_4)_2(s)darr`

The nitrate and the barium ions are along for the ride. I leave it to you to write the formula equation.
