What is the net ionic equation of reaction of MgCl2 with NaOH?

I got the equation and then balanced it and then omitted the spectator ions and ended up with:

Mg(OH)2(aq)--->Mg(OH) (s)

I wanted to confirm to see if that was correct, thanks.

Close but no cigar.

Full equation is
MgCl2(aq) + 2NaOH(aq) ==> Mg(OH)2(s) + 2NaCl(aq)

Those (aq) reagents are put in ionic form.
Mg^2+(aq) + 2Cl^-(aq) + 2Na^+(aq) + 2OH^-(aq) ==> Mg(OH)2(s) + 2Na^+(aq) + 2Cl^-(aq)

Then cancel 2Cl^- and 2Na^+ since they appear on both sides and you are left with
Mg^2+(aq) + 2OH^-(aq) ==> Mg(OH)2(s)

The net ionic equation for the reaction between MgCl2 (magnesium chloride) and NaOH (sodium hydroxide) is:

Mg2+(aq) + 2OH-(aq) -> Mg(OH)2(s)

So, your result of Mg(OH)2(s) is correct.

To determine the net ionic equation for the reaction between MgCl2 (magnesium chloride) and NaOH (sodium hydroxide), you need to follow a step-by-step process. Here's how you can do it:

Step 1: Write the balanced molecular equation.
The molecular equation for this reaction is:
MgCl2(aq) + 2NaOH(aq) → Mg(OH)2(s) + 2NaCl(aq)

Step 2: Check for the solubility of the compounds.
MgCl2 is soluble in water, so it remains in its ionic form: Mg2+(aq) + 2Cl-(aq)
NaOH is also soluble in water and dissociates into its ionic form: 2Na+(aq) + 2OH-(aq)

Step 3: Identify the spectator ions.
The spectator ions are those ions that appear on both sides of the equation without undergoing any change. In this case, Na+ and Cl- are the spectator ions.

Step 4: Write the net ionic equation.
To obtain the net ionic equation, we omit the spectator ions from the molecular equation. The net ionic equation for the reaction is:
Mg2+(aq) + 2OH-(aq) → Mg(OH)2(s)

Therefore, your initial response of Mg(OH)2(aq) → Mg(OH)2(s) is almost correct, except that you forgot to balance the equation properly. The correct net ionic equation for the reaction of MgCl2 with NaOH is:
Mg2+(aq) + 2OH-(aq) → Mg(OH)2(s)

Remember, balancing equations and identifying spectator ions are crucial steps in determining net ionic equations.
