A. The measured pH of a 0.100 M HCl solution at 25 degrees Celsius is 1.092. From this information, calculate the activity coefficient of H+.B. The measured pH of a solution of 0.010 HCl and 0.090 KCl at 25 degree Celsius is 2.102. Calculate the activity coefficient of H+ in this solution. C. Why does the pH change in part B relative to that in part A?

activity coefficient

activity coefficient

The change in pH in part A = 0.092

The change in pH in part B =  0.102

Explanation:

From the given information:

pH of HCl solution = 1.092

Activity of the pH solution [a] =

[a] = 0.0809 M

Recall that [a] = × C

where;

 = activity coefficient

C = concentration

Making the activity coefficient the subject of the formula, we have:

B.

The pH of a solution of HCl and KCl = 2.102

[a] =

[a] = 0.00791 M

activity coefficient

C. The change in pH in part A = 1.091 - 1.0 = 0.092

The change in pH in part B = 2.102 -2.00 = 0.102

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
