Write a chemical equation for the hydrolysis reaction that explains why an aqueous solution of CH3NH3Cl is acidic. [Please include the states of matter with each chemical species. Remember, it is an equilibrium reaction.]

CH3NH3Cl(aq) + H2O(l) <==> CH3NH2Cl- (aq) + H3O+(aq)

Explanation:

As CH3NH3Cl upon hydrolysis produces hydronium ions H3O+, the solution is acidic and can turn the color of blue litmus red.

Hydronium ion can donate its proton to the components of the litmus to react and give a reddish product.

Since it is an equilibrium reaction, the reverse arrows are used to indicate forward and backward reaction.
