Question

Assertion: The addition of a crystal of $I_2$ to $NaBr$ turns the solution violet.

Reason: $NaBr$ can reduce $I_2$ in a solution.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

Answer: (C)

Assertion is true but Reason is false

Because no redox reaction occur.
Since the reduction potential of $B{r}_2$ > reduction potential of $I_2$.
The reaction possible is :
Hence, a redox reaction between $B{r}^{⊝}and{I}_2$ is not possible and therefore violet colour of $I_2$ appear in the solution.
