Write the total ionic equation for the reaction of hydrofluoric acid with potassium hydroxide. 1. koh(aq) hf(aq) → kf(s) h2o(ℓ) 2. k (aq) oh−(aq) hf(aq) → k (aq) f−(aq) h2o(ℓ) 3. koh(s) h (aq) f−(aq) → k (aq) f−(aq) h2o(ℓ) 4. k (aq) oh−(aq) h (aq) f−(aq) → k (aq) f−(aq) h2o(ℓ) 5. koh(aq) hf(aq) → kf(aq) h2o(ℓ) 6. k (aq) o2−(aq) h (aq) h (aq) f−(aq) → k (aq) f−(aq) o2−(aq) 2 h (aq) 7. k (aq) oh−(aq) h (aq) f−(aq) → kf(s) h2o(ℓ)

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)
