The degree of dissociation of weak elect...

The degree of dissociation of weak electrolyde is inversely proportional to the square root fo concentration. It is called Ostwald's dilution law.
`alpha = sqrt((K_(a))/(c))` As the tempertaure increases, degree of dissociation will increase.
`(alpha_(1))/(alpha_(2)) = sqrt((K_(a_(1)))/(K_(a_(2))))` if concentration is same.
`(alpha_(1))/(alpha_(2)) = sqrt((c_(2))/(c_(1)))` if acid is same.
`0.01M CH_(3)COOH` has `4.24%` degree of dissociation, the degree of dissociation of `0.1M CH_(3)COOH` will be

A

`1.33%`

B

`4.24%`

C

The correct Answer is:
To solve the problem, we will use Ostwald's dilution law, which relates the degree of dissociation of a weak electrolyte to its concentration. Here are the steps to find the degree of dissociation of 0.1 M CH₃COOH given that 0.01 M CH₃COOH has a degree of dissociation of 4.24%. ### Step-by-Step Solution: 1. **Identify Given Values:** - Degree of dissociation (α₁) for 0.01 M CH₃COOH = 4.24% - Concentration (C₁) = 0.01 M - Concentration (C₂) = 0.1 M - We need to find the degree of dissociation (α₂) for 0.1 M CH₃COOH. 2. **Use the Ostwald's Dilution Law Formula:** Since the acid is the same, we can use the formula: \[ \frac{\alpha_1}{\alpha_2} = \sqrt{\frac{C_2}{C_1}} \] 3. **Substitute the Known Values:** \[ \frac{4.24}{\alpha_2} = \sqrt{\frac{0.1}{0.01}} \] Simplifying the right side: \[ \sqrt{\frac{0.1}{0.01}} = \sqrt{10} \approx 3.162 \] 4. **Set Up the Equation:** \[ \frac{4.24}{\alpha_2} = 3.162 \] 5. **Solve for α₂:** Rearranging the equation gives: \[ \alpha_2 = \frac{4.24}{3.162} \] Performing the calculation: \[ \alpha_2 \approx 1.34\% \] 6. **Conclusion:** The degree of dissociation of 0.1 M CH₃COOH is approximately 1.34%. ### Final Answer: The degree of dissociation of 0.1 M CH₃COOH is **1.34%**.
