A weak monobasic acid is 0.05 %0.05\ \% dissociated in its solution, find the degree of dissociation.

Options

  1. A2×10−42 \times 10^{-4}
  2. B4×10−24 \times 10^{-2}
  3. C5×10−45 \times 10^{-4}
  4. D2×10−22 \times 10^{-2}

Correct answer

C. 5×10−45 \times 10^{-4}

Step-by-step solution

The percentage dissociation of the weak monobasic acid is given as 0.05%0.05\%.

The degree of dissociation α\alpha is the fraction of the total amount of substance that is dissociated.

α=Percentage dissociation100\alpha = \dfrac{\text{Percentage dissociation}}{100}

α=0.05100\alpha = \dfrac{0.05}{100}

α=5×10−4\alpha = 5 \times 10^{-4}

Answer: 5×10−45 \times 10^{-4}
