It is found that `0.1M` solution of three sodium salts `NaX, NaY`, and `NaZ` have pH 7.0, 9.0 and 11.0, respectively. Arrange the acids (HX, HY, and HZ) in order of increasing acidic character. Calculate dissociation constant of acids.

Explanation

To solve the problem step by step, we will first analyze the pH values of the sodium salts and then determine the acidic character of the corresponding acids. Finally, we will calculate the dissociation constants of the acids.

### Step 1: Analyze the pH Values
We have three sodium salts:
- NaX with pH = 7.0
- NaY with pH = 9.0
- NaZ with pH = 11.0
