Chapter 18, Problem 67A

Which of the beakers shown in Figure 18.29 might contain a solution of $0.1M$ hypochlorous acid? Explain your answer.

Interpretation Introduction

Interpretation:

The beaker containing $0.1M$ hypochlorous acid is to be determined.

Concept introduction:

The concept of strong and weak acid is used to explain the result.

Strong acid ionizes completely into its ions in aqueous solution but weak acid ionizes to some extent in aqueous solution.

Answer to Problem 67A

The beaker shown on right side might contain $0.1M$ hypochlorous acid because hypochlorous acid is weak acid and weak acids are not completely ionized so it conducts less electricity. And there should be lesser glow.

Explanation of Solution

Hypochlorous acid should be in beaker shown on right side because it is not glowing properly indicating less conductivity.

Conclusion

Thus weak acids conduct electricity to less extent than strong acids.
