Answer:
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.
