Question

When a strong acid reacts with a strong base the pH at the point of neutralisation is pH 7. If

a strong base reacts with a weak acid, do you expect the point of neutralisation to be above,
below or at the pH of 7? Explain.

Answer 1

When a strong base reacts with a weak acid, the point of neutralization will be above pH 7.

Step-by-step explanation:

When a strong base reacts with a weak acid, the point of neutralization will be above pH 7. This is because the resulting solution will be basic, meaning it will have a higher pH value. The weak acid is not able to fully neutralize the strong base, resulting in an excess of hydroxide ions (OH-) in the solution, which increases the pH.
