Answer : The pH of the solution is, 4.2
Explanation : Given,
Concentration of = 0.10 M
Concentration of = 0.030 M
First we have to calculate the value of .
The expression used for the calculation of is,
Now put the value of in this expression, we get:
Now we have to calculate the pH of buffer.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Therefore, the pH of the solution is, 4.2
