Question

Which process uses a volume of solution of known concentration to determine the concentration of another solution?

(1) distillation (3) transmutation(2) substitution (4) titration

Answer 1

Titration. The known is added to the unknown until it reaches an equilibrium.

Answer 2

Answer: Titration

Explanation: Titration is defined as the process where a solution of known concentration is used to determine the concentration of an unknown solution.

Volumetric titrations are usually used for neutralization reactions where an indicator is used to know the acidic or basic nature of solution.

The normality equation used at a point where neutralization occurs during the titration is:

`N_1V_1=N_2V_2`

`N_1`= Normality of acid solution

`V_1` = volume of acid solution

`N_2`= Normality of basic solution

`V_2`= Volume of basic solution
