Question

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

Answer 1

Answer: 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.

Answer 2

Answer - Determining the concentration of an unknown base

In any titration procedure, the final step would usually be to determine the concentration of the unknown substance, be it the acid or the base. All the other steps listed in the question above are carried out in order to eventually come to the correct calculation of the concentration.
