Answer : The concentration of the
is, 0.115 M
Explanation :
Using dilution law,

where,
= basicity of an acid = 1
= acidity of a base = 1
= concentration of
= 0.125 M
= concentration of KOH = ?
= volume of
= 25 ml
= volume of NaOH = 27.07 ml
Now put all the given values in the above law, we get the concentration of the
.


Therefore, the concentration of the
is, 0.115 M
