Question 2 0.5 pts Consider the following Ka values; acetic acid chloroacetic acid hypochlorous acid KalHCIO (aq)] -2.90 x 10-8 hydrofluoric acid KJHF (aq) 6.30 x 104 formic acid Which of the following is a correct statement? Ka[CH3COOH (aq)] = 1.80 x 10-5 KalCH2C|COOH (aq)] = 1.40 x 10-3 Ka[HCOOH (aq)] = 1.80 x 10-4 Acetic acid is a weaker acid than hypochlorous acid Chloroacetic acid is the strongest acid on the list Formic acid is a weaker acid than hydrofluoric acid Formic acid is a stronger acid than acetic acid Hypochlorous acid is the weakest acid listed

Explanation / Answer

Ka is indicator of acid strength. Higher Ka value indicates higher acidic nature

Based on this

Chloroacetic acid is the strongest on the list

Formic acid is weaker than hydroflouric acid

Formic acid is stronger than acetic acid

Hypochlorous acid is weakest acid
