Question

The diagram represents the preparation of sodium sulphate salt from dilute $H_{2}S{O}_4$ acid and sodium hydroxide. State the reason for conducting the titration using the apparatus $A$ and $B$?

• A. Making solution acidic
• B. To know end point of the reaction
• C. To measure volumes of solution accurately
• D. Formation of sodium sulphate

Answer 1

Answer: (C)

To measure volumes of solution accurately

Sodium hydroxide measured, taken in the flask and titrated by sulfuric acid until it is neutralized. Evaporation of the solution is done on a Bunsen burner flame and pour the into a crystallizing dish. Sodium sulfate crystals are formed.
