Hello,
In this case, the reaction between sulfuric acid and potassium hydroxide is:
In such a way, we notice a 1:2 molar ratio between the acid and the base, therefore, at the equivalence point we have:
And in terms of concentrations and volumes:
Thus, we solve for the volume of acid:
Best regards.
The molecular mass of is: 1·1 + 1·14.01 + 2·16 = 47.01 g/mol.
Now we can convert the mass into mol of :
