Question

Which of the following acids is the weakest? The acid is followed by its Ka value.

Option 1: HF, 6.8 × 10^-4
Option 2: CH3COOH, 1.8 × 10^-5
Option 3: HClO2, 1.1 × 10^-2
Option 4: HClO, 2.9 × 10^-8
Option 5: HNO2, 4.6 × 10^-4

Answer 1

HClO is the weakest acid among the options provided, with a Ka value of 2.9 x 10^-8.

Step-by-step explanation:

The weakest acid among the given options is HClO, with a Ka value of 2.9 x 10-8. A smaller Ka value indicates a weaker acid. Comparing the Ka values, HClO has the lowest value, making it the weakest acid.
