    A certain monobasic acid (weak) serves as indicator. Assuming that colour change is seen when \[\frac{1}{3}\,rd\] of the indicator has been converted 3 to ions and that at end point the pH of solution is 6. What is the value of \[p{{K}_{In}}\]-

    A) 5.533               

    B) 0.301

    C) 6.477               

    D) 6.301

    Correct Answer: D

    Solution :

    \[pH=p{{K}_{In}}\,\,+\,\,\log \,\frac{1/3}{2/3}\] \[p{{K}_{In}}\,\,6+.301=6.301\]
