    1.

    The pH value of decinormal solution of NH4OH which is 20% ionised is

    • 12.95

    • 12.30

    • 14.70

    • 13.30

    B.

    12.30

    Concentration NH4OH solution = 0.1 N

    Concentration of OH ions in solution, 

    [OH-] = 20% of 0.1N =20100×0.1

    pOH = -log[OH-] = -log(0.02)                                    = 2- 0.301pH = 14-pOH = 12.30

    Answer
    2.

    Which of the following is strongest Bronsted base?

    • ClO-

    • ClO2-

    • ClO3-

    • ClO4-

    A.

    ClO-

    HClO4 is the strongest acid among HClO, HClO2, HClO3, and HClO4 as more the number of oxygen atoms attached, more is the acidity of the molecule order of acidity is :

    HClO < HClO2 < HClO3 < HClO4

    So the conjugate base order will be just reverse:

    ClO- > ClO2- > ClO3- > ClO4-
