2. HF (aq) + K^ (+) (aq) + OH^ (-) (aq) → K^ (+) (aq) + F^ (-) (aq) + H_2O (ℓ)

Step 1. Write the molecular equation

HF (aq) + KOH (aq) → KF (aq) + H_2O (ℓ)

Step 2. Write the total ionic equation

HF and H_2O are weak electrolytes, so we write them as molecules.

HF (aq) + K^ (+) (aq) + OH^ (-) (aq) → K^ (+) (aq) + F^ (-) (aq) + H_2O (ℓ)
