The following chemical reaction takes place in aqueous solution: MgBr2 (aq) + 2KOH (aq) →Mg (OH) 2 (s) + 2KBr (aq) Write the net ionic equation for this reaction.

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.
