Question 8 • Chemistry

Which describes the titration graph when a weak acid is titrated by a strong base?

Answer
A
It begins at a low pH and has an equivalence point greater than 7 .
B
It begins at a high pH and has an equivalence point less than 7 .
C
It begins at a high pH and has an equivalence point of 7 .
D
It begins at a low pH and has an equivalence point of 7 .

Explanation

A weak acid starts at a low pH because the solution is acidic. At the equivalence point, the weak acid has been neutralized, leaving its conjugate base, which reacts with water to make the solution basic; therefore, the equivalence-point pH is greater than 7. This matches “begins at a low pH and has an equivalence point greater than 7.”
