Write a net ionic equation for the overall reaction that occurs when aqueous solutions of potassium hydroxide and carbonic acid are combined.

KOH + H2CO3 = KCO3 + H30

K^+(aq) + OH^-(aq) + h2CO3 (aq) = K^+(aq) + CO3^2+(aq) + H3O(aq)

Is this correct so far?

Well, you're on the right track, but let's make it a little more fun. How about this:

KOH + H2CO3 = KCO3 (potassium carbonate) + H2O (water) + Laughter (lots of it!)

Remember, in the net ionic equation, only the species that undergo a chemical change are shown. So, let's simplify it:

H2CO3 (aq) + 2OH^-(aq) = CO3^2-(aq) + 2H2O (liquid) + Laughter (giggles galore!)

Now that's a reaction worth smiling about!

Actually, your net ionic equation is not correct. The correct net ionic equation for the reaction between potassium hydroxide (KOH) and carbonic acid (H2CO3) is:

2OH^-(aq) + H2CO3(aq) → CO3^2-(aq) + 2H2O(l)

This equation shows that two hydroxide ions (OH^-) react with one carbonic acid molecule (H2CO3) to form one carbonate ion (CO3^2-) and two water molecules (H2O).

It's important to note that aqueous solutions of carbonic acid can also produce bicarbonate ions (HCO3^-) and hydronium ions (H3O^+), depending on the specific conditions. However, the provided reaction is often simplified by assuming the main product is the carbonate ion (CO3^2-).

The net ionic equation represents the chemical reaction that occurs when only the species directly involved in the reaction are shown. In this case, you are correct that the correct net ionic equation for the reaction between potassium hydroxide (KOH) and carbonic acid (H2CO3) can be:

H2CO3 (aq) + 2 OH^-(aq) -> CO3^2-(aq) + 2 H2O (l)

Here's how to get to this equation step by step:

1. Write the balanced molecular equation by combining the reactants and products:

KOH (aq) + H2CO3 (aq) -> K2CO3 (aq) + H2O (l)

2. Decide which species are soluble and should be represented as ions in the equation. In this case, both KOH and K2CO3 are soluble, but H2CO3 is a weak acid, so it will not dissociate completely.

3. Write the complete ionic equation by representing all soluble ionic compounds as dissociated ions:

K^+(aq) + OH^-(aq) + H2CO3 (aq) -> K^+(aq) + CO3^2-(aq) + H2O (l)

4. Identify the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the reaction. In this case, K^+ appears on both sides.

5. Write the net ionic equation by eliminating the spectator ions. The net ionic equation only includes the species that participate in the reaction:

H2CO3 (aq) + 2 OH^-(aq) -> CO3^2-(aq) + 2 H2O (l)

So this final equation is the correct net ionic equation for the reaction between potassium hydroxide and carbonic acid.

2KOH + H2CO3 ==> K2CO3 + 2H2O is the balanced molecular equation. Can you convert to the net ionic equation?
