Answer:
Net ionic equation is: Mg∧+2 + 2OH∧-1 → Mg(OH)2 (s)
Explanation:
Chemical equation:
MgBr2 + KOH → Mg(OH)2 + 2KBr
Balance chemical equation with physical states:
MgBr2(aq) + 2KOH(aq) → Mg(OH)2(s) + 2KBr(aq)
Ionic equation:
Mg∧+2 + 2Br∧-1 + 2K∧+1 + 2OH∧-1 → Mg(OH)2 (s) + 2K∧+1 +2Br∧-1
Net ionic equation:
Mg∧+2 + 2OH∧-1 → Mg(OH)2 (s)
2Br∧-1 and 2K∧+1 ions are spectator ions that's way these are not written in net ionic equation.
Spectator ions:
These are the ions that are present same on both side of chemical reaction and does not effect the equilibrium.
