Write a chemical equation for the hydrolysis reaction that explains why an aqueous solution of ch3nh3cl is acidic.

CH₃-NH₃Cl + NaOH → CH₃-NH₂ + NaCl + H₂O

Now we may say that CH₃-NH₃Cl have an acidic character because it can react with a base.

CH₃NH₃Cl (aq) + H₂O (l) → CH₃NH₂Cl⁻ (aq) + H₃O⁺ (aq)

Explanation:

The hydrolysis reaction (meaning the breaking of the substance when reacting with water) of CH₃NH₃Cl is:

CH₃NH₃Cl (aq) + H₂O (l) → CH₃NH₂Cl⁻ (aq) + H₃O⁺ (aq)

An aqueous solution of CH₃NH₃Cl is acidic because it produces hydronium ions (H₃O⁺).
