Atitration is performed to determine the concentration of an unknown acid. which piece of equipment is best suited to perform this experiment?

The piece of equipment that is best suited to perform this experiment is the burette. Acid-base titrations are used to determine the concentration of a sample of acid or a base and are carried out using a burette. The solution whose concentration is known is called a standard solution. Therefore in the unknown sample is an acid then the standard solution in the burette needs to be a base since the aim is to see at what point the unknown sample is neutralized. 

Neurotransmitters are messengers responsible for communication between neurons. they are released from synaptic vesicles and are received by receptors.  the communication is referred to as neurotransmission. the following statement is true about neurotransmitters: a. they're stored in synaptic vesicles in the axon.
