Answer:
E: the point where the acid and base have been added in proper stoichiometric amounts
Explanation:
Equivalence point in titration is simply the point where the amounts of acid and base used just sufficiently reacts chemically to cause neutralization whereas the endpoint is the point where the indicator of the titration changes colour.
The Equivalence point occurs before the endpoint.
Thus, option E is correct.

Answer:
A suction bulb or pipette pump to suction the sample.
Explanation:
There are different types of pipettes that can be used in a laboratory:
- Volumetric pipette-used to transfer a specific calculated amount of liquid
- Graduated pipettes-used to transfer different calculated amounts of liquid from one container to another.
- Micropipettes-used to transfer small amounts of liquids
- Pasteur pipettes- just like micropipettes, pasteur pipettes are used to transfer small amounts of liquids, but manually. They are also called droppers.
