Law of Chemical equilibrium -

At a given temperature, the product of concentration of the reaction products raised to the respective stoichiometric coefficient in the balanced chemical equation divided by the product of concentration of the reactants raised to their individual stoichiometric coefficients has a constant value.

- wherein

aA+bB\rightleftharpoons cC+dD


K_{c}=\frac{[C]^{c\:[D]^{d}}}{[A]^{a}\:[B]^{b}}

[A],\:[B],\:[C]\:[D]

are equilibrium concentration

 

 Acidic Buffer is a mixture of a weak acid and its salt with a strong base. HClOis a strong acid.

 


Option 1)

HClO_{4}\ and\ NaClO_{4}

correct

Option 2)

CH_3COOH\ and\ CH_3COONa

incorrect

Option 3)

H_2CO_3\ and\ Na_2CO_3

incorrect

Option 4)
