When a strong acid is titrated with a weak base, the pH at the equivalence point

Question

a. is greater than 7.0.

b. is equal to 7.0.

c. is less than 7.0.

d. is equal to the pKa of the acid.

e. is equal to the pKb of the base.

Answer 1

B - that's the definition of equivalence point, when the acid and base neutralize each other

Answer 2

c. is less than 7.0.  

Answer 3

c. is less than 7.0.

it does not mean that the pH=7 (neutral) at the equivalence point

the equivalence point is the point where the amount of titrant added is equivalent, or equal, to the amount of analyte present in the sample cause they react with eachother in a certain ratio.
