A solution of malonic acid, H2C3H2O4 , was standardized by titration with 0.1000 M NaOH solution. If 21.17 mL of the NaOH solution were required to neutralize completely 12.70 mL of the malonic acid solution, what is the molarity of the malonic acid solution

The molarity of the malonic acid solution is 0.08335 M

Explanation:

To calculate the molarity 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:

Thus the molarity of the malonic acid solution is 0.08335 M
