Problem Details
Consider the three generic weak acids HA, HB, and HC. The images shown here represent the ionization of each acid at room temperature.
The figure shows 3 diagrams of 3 acids at room temperature. Diagram of acid HA contains 23 molecules, 1 red and 1 white ball. Each molecule consists of 1 red and 1 white ball. Diagram of acid HB contains 20 molecules, 4 blue and 4 white balls. Each molecule consists of 1 blue ball and 1 white ball. Diagram of acid HC contains 24 molecules, 2 green and 2 white balls. Each molecule consists of 1 green ball and 1 white ball.
Which acid has the largest Ka?
