MTTC Chemistry - Additional Info Sample Questions

When a strong acid reacts with a weak base, what will be the pH of the resulting solution?

Correct Answer:
less than seven (7).


when a strong acid reacts with a weak base, the ph of the resulting solution will generally be less than seven (7). this is because of how strong acids and weak bases behave in water.

strong acids, which include substances like hydrochloric acid (hcl) and sulfuric acid (h₂so₄), are characterized by their ability to completely dissociate into their constituent ions in solution. for example, hcl in water dissociates completely into h⁺ and cl⁻ ions. this complete ionization results in a high concentration of hydrogen ions (h⁺) in the solution.

on the other hand, weak bases, such as ammonia (nh₃), do not fully ionize in solution. when a weak base like nh₃ is added to water, it reacts to form nh₄⁺ (ammonium) and oh⁻ (hydroxide) ions, but only a small fraction of the nh₃ molecules convert to nh₄⁺. most of the nh₃ remains as nh₃ molecules in solution.

during the reaction between a strong acid and a weak base, the abundant h⁺ ions from the strong acid will react with the limited oh⁻ ions produced by the weak base. since the base is weak and does not fully neutralize the acid, it results in an excess of h⁺ ions.

the excess h⁺ ions increase the acidity of the solution, leading to a ph that is less than 7. the exact ph value can vary depending on the concentrations and specific properties of the acid and base involved, but it will invariably be on the acidic side of the ph scale due to the predominance of hydrogen ions.

therefore, when predicting the ph of a solution resulting from the reaction between a strong acid and a weak base, it is safe to conclude that the ph will be less than seven, indicating an acidic environment.
