You have 185 ml of an acid with an unknown concentration. to determine the concentration you decide to use a 0.85 m solution of sodium hydroxide to titrate the acid. after the titration you determined that it took 35.7 ml of the 0.85 m solution of sodium hydroxid to reach the endpoint. what is the acids concentration?

Explanation:

The given data is as follows.

        = ?,         = 0.85 M

        = 185 mL,     = 35.7 mL

where, is concentration of acid

            is the volume of acid

            is the concentration of base

            is the volume of base

According to the neutralization formula.

          =

Now, substituting the given values into the above formula as follows.

          =

          =

                        = 0.164 M

Thus, we can conclude that concentration of acid is 0.164 M.
