    Ans.

    Given density of formic acid = 1.22 g/cm
    ∴ Weight of formic acid in 1 litre solution = 1.22 x 10

    The self-ionization constant for pure formic acid, K = [HCOOH2+] [HCOO...
    The self-ionization constant for pure formic acid, K, is the equilibrium constant for the reaction:

    HCOOH ⇌ H+ + HCOO-

    The expression for the self-ionization constant is:

    K = [H+][HCOO-] / [HCOOH]

    Where [H+] represents the concentration of H+ ions, [HCOO-] represents the concentration of HCOO- ions, and [HCOOH] represents the concentration of formic acid.

    Note that in the expression, we do not include the subscript 2 after HCOOH, as it is not necessary for the self-ionization constant calculation.
