Which of the following solutions will have the highest conductivity at 298 K?(a) 0.01 M HCl solution (b) 0.1 M HCl solution(c) 0.01 M CH 3COOH solution (d) 0.1 M CH 3COOH solution

The solution with the highest conductivity at 298 K would be the 0.1 M HCl solution.

Here's why:

1. Conductivity of a solution depends on the number of ions present in the solution. The more ions there are, the higher the conductivity.

2. HCl is a strong acid, which means it completely ionizes in solution. This means that a 0.1 M HCl solution will have more ions than a 0.01 M HCl solution.

3. CH3COOH, on the other hand, is a weak acid and does not completely ionize in solution. This means that even at higher concentrations, there will be fewer ions present than in a solution of a strong acid at the same concentration.

4. Therefore, out of the given options, the 0.1 M HCl solution will have the highest conductivity at 298 K.
