  • Acidic solution is defined as a solution whose [H^(o+)] gt [overset(Theta)OH] . Base solution has [overset(Theta)OH] gt [H^(o+)] . During acid-base titrations, pH of the mixture will change depending on the amount base added. This variation is shown in the form of graph by making plot as titration curves 100mL of 1.0 M H_(3)A (K_(a_(1)) = 10^(-3), K_(a_(2)) = 10^(-5), K_(a_(3)) = 10^(-7)) is titrated against 0.1M NaOh . The titration curve is as follows. What will be the change in pH from point B to point C?

    A
    `2.8`
    B
    `3.2`
    C
    `4.6`
