Which of the following is the last step in performing a titration? finding out which ph indicator works determining the concentration of an unknown base finding the number of moles of product produced in a reaction determining the molecular masses of the products in the reaction

  Determining the concentration of an unknown base

Explanation:   While performing a titration,below mentioned steps are followed in the written order -

a)  Finding out which pH indicator works - this is the important and the initial step

b)  After that , one will determine the molecular masses of the products formed in the reaction.

c)  After  determining the molecular mass, number of moles of the product are calculated in order to reach to the conclusion.

d) Thus the final step would be the determiation of the concentration of the unknown base.
