Which describes the titration graph when a weak acid is titrated by a strong base? a) it begins at a low ph and has an equivalence point of 7. b) it begins at a low ph and has an equivalence point greater than 7. c) it begins at a high ph and has an equivalence point of 7. d) it begins at a high ph and has an equivalence point less than 7.

B) It begins at a low pH and has an equivalence point greater than 7.

Explanation: We know the pH of acids is less than 7 and the pH of bases is greater than 7. Stronger is the acid, lower is the pH and weaker is the acid, slightly higher would be the pH(less than 7).

For bases, weaker is the base lower is the pH(greater than 7) and stronger is the base, higher is the pH.

If we titrate a weak acid with a strong base then at equivalence point the solution will be basic and due to basic in nature, the pH at the equivalence point will be greater than 7.

If we look at all the given choices then its only choice B that says the equivalence point pH will be greater than 7.

So, the correct choice is B.
