Which of the following is true?
A)The equivalence point is where the amount of acid equals the amount of base during any acid-base titration.
B)At the equivalence point,the pH is always 7.
C)An indicator is not pH sensitive.
D)A titration curve is a plot of pH vs.the [base]/[acid] ratio.
E)None of the above are true.

Question

Quizplus · Accepted Answer

The equivalence point is defined as the point during an acid-base titration where the moles of acid and base are equal, which is represented by the stoichiometric point in the titration curve. Therefore, choice A is correct. Choice B is not always true because it depends on the acid and base being titrated. Choice C is false because indicators are specifically chosen for their pH sensitivity. Choice D is also not entirely true- while a titration curve can involve plotting pH against [base]/[acid], it can also involve plotting pH against volume of titrant added.
