Equivalent conductance of 0.1 M HA (weak acid) solution is 10 $\mathrm{S}\mathrm{c}{\mathrm{m}}^2$ equivalent ${\mathrm{}}^{-1}$ and that at infinite dilution is 200 $\mathrm{S}\mathrm{c}{\mathrm{m}}^2$ equivalent ${\mathrm{}}^{-1}$. Hence pH of HA solution is

• A

  1.3
• B

  1.7
• Correct answer
  C

  2.3
• D

  3.7

Hence, the correct answer is option: 'C'.
