Chapter 18, Problem 74A

Interpretation Introduction

Interpretation:

The procedure of preparing dilute solution of strong acid and concentrated solution of weak acid is to be explained.

Concept introduction:

Concentrated solution: A solution in which concentration of solute is high.

Dilute solution: A solution in which concentration of solute is low.

Answer to Problem 74A

Dilute solution of strong acid can be prepared by taking small amount of strong acid and adding it to a large quantity of water.

Concentrated solution of weak acid can be prepared by taking large quantity of weak acid and adding it in small quantity of water.

Explanation of Solution

To prepare dilute solution, volume of water should be more than acid and to prepare concentrated solution, volume of water should be less than acid.

Always add acid in water in small lots with constant shaking to make the solution.

Conclusion

Thus, dilute solution of strong acid is prepared by taking small amount of strong acid and adding it to a large quantity of water. Concentrated solution of weak acid is prepared by taking large quantity of weak acid and adding it in small quantity of water with constant stirring.
