You dispose of a $0.200\;M$ solution of $H_3C_6H_5O_7$
(citric acid, $K_a$ $=$ $3.5\cdot 10^{-4}$)
Equilibrium of hydrolysis:
$H_3C_6H_5O_7$ $+$ $H_2O$
$H_3O^+$ $+$ $H_2C_6H_5O_7^-$
To which side will the reaction shift in order to attain the equilibrium ?
a) to the left side b) to the right side c) The reaction will not shift because equilibrium is already attained.
The reaction will shift to b) the right side
