Explanation:
The reaction equation will be as follows.
Hence, the expression for is as follows.
Let us assume that the concentration of both and
is x.
x = 0.01118034
This means that the concentration of is 0.01118034.
Since, we know that the relation between pH and concentration of hydrogen ions is as follows.
pH =
=
= 1.958
Thus, we can conclude that the pH of a 0.500 M solution of arsenic acid is 1.958.
