By titration, it is found that 95.5 ml95.5 ml of 0.188 m naoh(aq)0.188 m naoh(aq) is needed to neutralize 25.0 ml of hcl(aq).hcl(aq). calculate the concentration of the hclhcl solution.

The concentration of HCl comes out to be 0.718 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 HCl

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

We are given:

Putting values in above equation, we get:

Hence, the concentration of HCl comes out to be 0.718 M.
