Answer:
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
Answer:
(a) A strong acid
Explanation:
We have given the pH of the solution is 2.46
pH=2.46
So the concentration of
solution having H+ concentration more than is acidic
Since in the given solution, H+ concentration is 0.00346 M which is more than 10^{-7}[/tex] so this is an acidic solution
Note-The concentration of decide the behavior of the solution that is, it is acidic or basic
