A beaker is filled with 225.0mL of sodium hydroxide solution with an unknown concentration. A 0.00100 M solution of HCI is used in the titration. the equivalence point is reached when 27.0mL of HCI have been added.What is the initial concentration of NaOH in the beaker

The titration formula is used when we have an equivalence point of neutralization between acid and base, the formula is:

Ma * Va = Vb * Mb

Where:

Ma = concentration of acid

Va = volume of acid

Mb = concentration of base

Vb = volume of base

This formula tells us the concentration and volume of an acid must be equal to the concentration and volume of a base in order to neutralize the reaction (this applies to strong acids and strong bases only)

Ma * Va = Vb * Mb

0.00100 * 27 = 225 * Mb

0.027 = 225Mb

Mb = 0.00012M
