# What is the net ionic equation for the reaction between HF and KOH?

• Drakkith
In summary, the net ionic equation for the reaction between hydrofluoric acid and potassium hydroxide is HF + KOH → KF + H2O. To determine the spectator ions, you need to first write the balanced molecular equation and then break it down into its ions. The ions that appear on both sides of the equation and cancel out are the spectator ions. The net ionic equation is important because it allows us to focus on the essential components of a chemical reaction and eliminates any spectator ions. The net ionic equation for the reaction between HF and KOH tells us that hydrofluoric acid and potassium hydroxide react to form potassium fluoride and water, and that the hydrogen ion and hydroxide ion combine to form

## Homework Statement

The net ionic equation for the reaction between aqueous solutions of HF and KOH is___.

## The Attempt at a Solution

At first I thought it would simply be H+ + OH- = H2O, with the K and F ions as spectator ions.
But the answer is apparently HF + OH- = H2O + F-.

Is this because HF is a weak acid that doesn't dissociate completely in water?

Yes. KOH is a strong base, fully dissociated, HF is a weak acid, dissociated only partially.

Thanks Borek!

## 1. What is the net ionic equation for the reaction between hydrofluoric acid and potassium hydroxide?

The net ionic equation for this reaction is HF + KOH → KF + H2O.

## 2. How do you determine the spectator ions in a net ionic equation?

To determine the spectator ions, you need to first write the balanced molecular equation and then break it down into its ions. The ions that appear on both sides of the equation and cancel out are the spectator ions.

## 3. Why is the net ionic equation important?

The net ionic equation allows us to focus on the essential components of a chemical reaction and eliminates any spectator ions that do not participate in the reaction. This makes it easier to understand and analyze the reaction.

## 4. What does the net ionic equation tell us about the reaction between HF and KOH?

The net ionic equation tells us that hydrofluoric acid and potassium hydroxide react to form potassium fluoride and water. It also shows that the hydrogen ion from hydrofluoric acid and the hydroxide ion from potassium hydroxide combine to form water.

## 5. How do you balance a net ionic equation?

To balance a net ionic equation, you need to first balance the atoms in the molecular equation, then break it down into its ions and balance the charges. Finally, make sure that the number of each type of ion is the same on both sides of the equation.
