    According to Henderson-Hasselbalch Equation,

    pH = pKa + log [Acetate] / [Acetic Acid]

    As, pKa of Acetic Acid = 1.76

    So, pH = 1.76 + log [Acetate] / [Acetic Acid]

    4.70 = 1.76 + log [Acetate] / [Acetic Acid]

    4.70 - 1.76 = log [Acetate] / [Acetic Acid]

    -0.04 = log [Acetate] / [Acetic Acid]

    Taking Antilog on both sides,

    [Acetate] / [Acetic Acid] = 0.912
