In a certain experiment a student finds that the PHs of 0.10 M solutions of three potassium salts KX, KY, and KZ are 7.0, 9.0, and 11.0, respectively. Arrange the acids HX, HY, and HZ in order of increasing acid strength.

To determine the order of increasing acid strength, we need to analyze the pH values of the corresponding salts. The lower the pH of a salt solution, the stronger the acid.

Given that the pHs of 0.10 M solutions of KX, KY, and KZ are 7.0, 9.0, and 11.0, respectively, we can infer the acid strengths as follows:

1. Salt KX has a pH of 7.0, which denotes a neutral solution. Therefore, HX is a weak acid.
2. Salt KY has a pH of 9.0, which is higher than 7.0. This indicates that KY is basic, meaning HY is a stronger acid than HX.
3. Salt KZ has a pH of 11.0, which is the highest among the three salts. This implies that KZ is basic, meaning HZ is the strongest acid.

Hence, the order of increasing acid strength is: HX < HY < HZ.

To determine the order of increasing acid strength for the acids HX, HY, and HZ, we need to analyze the pH values of their corresponding potassium salts.

The pH of a solution is a measure of how acidic or basic it is. A lower pH value indicates a more acidic solution, while a higher pH value indicates a more basic solution.

In this experiment, the student finds that the pH values of the 0.10 M solutions of the potassium salts KX, KY, and KZ are 7.0, 9.0, and 11.0, respectively.

Since potassium salts are formed by the reaction of an acid with a base, the pH of the solution of the potassium salt can give us information about the strength of the corresponding acid.

A solution with a pH of 7.0 is considered neutral, which means the corresponding acid and base are equally strong.

A solution with a pH of 9.0 is more basic, indicating that the acid is weaker than the acid corresponding to a pH of 7.0.

A solution with a pH of 11.0 is even more basic, indicating that the acid is weaker than the acids corresponding to pH values of 7.0 and 9.0.

Therefore, based on the pH values, we can conclude that HX is the strongest acid (pH 7.0), HY is the second strongest acid (pH 9.0), and HZ is the weakest acid (pH 11.0).

In summary, the order of increasing acid strength for HX, HY, and HZ is: HZ < HY < HX.

Write the hydrolysis equations. For x it will be

........X^- + HOH ==>HX + OH^-
I......0.1...........0.....0
C......-x............x.....x
E.....0.1-x..........x.....x

Kb for X^- = (Kw/Ka for HX) = (x)(x)/).1-x
Since pH = 7 that makes pOH = 7 and (OH^-) = x = 1E-7. Solve for Ka. You may need to use the quadratic.

Do the same for Y and Z salts, solve for Ka for HY and HZ then you will have
Ka for HX, HY, and HZ and arrange them in order of increasing acid strength which will be in order of increasing Ka.
