JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Hydrogenion concentration pH scale and buffer solution

  • question_answer
    The one which has the highest value of \[pH\]is

    A)                 Distilled water  

    B)                 \[N{{H}_{3}}\]Solution in water

    C)                 \[N{{H}_{3}}\]

    D)                 Water saturated with \[C{{l}_{2}}\]

    Correct Answer: B

    Solution :

               In water solution.                    \[N{{H}_{3}}+{{H}_{2}}O\] ⇌ \[NH_{4}^{+}+O{{H}^{-}}\] Concentration of \[O{{H}^{-}}\]is increased so that solution become more basic and the pH is increased.
