K_{a_1}

,

K_{a_2}

and

K_{a_3}

are the respective ionization constants for the following reactions (a), (b) and (c). (a)

\mathrm{H_2C_2O_4} \rightleftharpoons \mathrm{H^+} + \mathrm{HC_2O_4^-}

(b)

\mathrm{HC_2O_4^-} \rightleftharpoons \mathrm{H^+} + \mathrm{C_2O_4^{2-}}

(c)

\mathrm{H_2C_2O_4} \rightleftharpoons 2\mathrm{H^+} + \mathrm{C_2O_4^{2-}}

The relationship between

K_{a_1}

,

K_{a_2}

and

K_{a_3}

is given as :

A
${K_{{a_3}}}={K_{{a_1}}}+{K_{{a_2}}}$
B
${K_{{a_3}}}={K_{{a_1}}}-{K_{{a_2}}}$
C
${K_{{a_3}}}={K_{{a_1}}}/{K_{{a_2}}}$
D
${K_{{a_3}}}={K_{{a_1}}}\times{K_{{a_2}}}$
