Question

What is the net ionic equation for the reaction Al(NO3)3+K2CrO4?

Answer 1

The reaction would be:

$3K_2CrO_4+2Al(NO_3)_3\rightarrow 6KNO_3+Al_2(CrO_4)_3$

But since Al₂(CrO4)₃ does no exist, the net ionic reaction would be the:

$6K^++3CrO_4^{2-}+2Al^{3+}+6NO_3^{-}\rightarrow 6K^++3CrO_4^{2-}+2Al^{3+}+6NO_3^{-}$

as you can see there is no change
