SUMMARY
The addition of HCl to the equilibrium system of NH3 + H2O <--> NH4+ + OH- causes the equilibrium to shift to the left, according to Le Chatelier's principle. This shift occurs as H+ ions from HCl react with OH- ions, forming water and reducing the concentration of OH- in the solution. Consequently, the pH of the solution decreases as the reaction proceeds, indicating increased acidity due to the presence of HCl.
