Question

MgSO4(aq) + 2 NH4OH(aq) → Mg(OH)2(s) + (NH4)2SO4(aq)

Answer 1

Whats your question?

Answer 2

what is the balanced net ionic equation to this problem?

Answer 3

From the equation its obvious that Mg(OH)2 is not ionic as it does not dissolve.
MgSO4 is Mg2+ and SO42-.
NH4OH is NH4+ and OH-.
NH4)2 SO4 is NH4+ and SO42-. But Mg(oh)2 is not ionic.
So writing the equation you have
\[Mg ^{2+}+SO _{4}^{2-}+2NH _{4}^{+}+2OH ^{-} -> Mg(OH)_{2} + 2NH4^{+}+SO _{4}^{2-}\] Now you can cancel NH4+ and SO42- from the equation as it is just spectator ions.
You are left with
\[Mg ^{2+}+ 2OH ^{-} -> Mg(OH)_{2}\]

Answer 4

thanks!

Answer 5

no problem.
