Exercise 14

Establish the hydrolysis equilibrium reaction of citric acid!

a) $H_3C_6H_5O_7$ $+$ $2H_2O$ $H_3O^+$ $+$ $H_5C_6H_5O_8^-$ b) $H_3C_6H_5O_7$ $+$ $H_2O$ $H_4C_6H_5O_7^+$ $+$ $OH^-$ c) $H_3C_6H_5O_7$ $+$ $H_2O$ $H_3O^+$ $+$ $H_3C_6H_4O_7^-$ d) $H_3C_6H_5O_7$ $ +$ $H_2O$ $H_3O^+$ $+$ $H_2C_6H_5O_7^-$

Here is the correct answer: d) $H_3C_6H_5O_7$ $+$ $H_2O$ $H_3O^+$ $ +$ $H_2C_6H_5O_7^-$
