23.24 mL of a solution of the acid H2SO4 is titrated, and 56.10 mL of 0.7200-M NaOH is required to reach the equivalence point. Calculate the original concentration of the acid solution. g

Answer : The original concentration of the acid solution is 0.869 M

Explanation :

To calculate the concentration of acid, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is NaOH.

We are given:

Putting values in above equation, we get:

Therefore, the original concentration of the acid solution is 0.869 M
