A quality control chemist at dow chemical tried to determine purity of naoh using titration. He measured out 0. 500 g naoh sample and dissolved it in 20 ml water. 22. 5 ml of a 0. 500 mol/l hcl solution was used to reach the end point. Assume the impurity did not react with hcl, what is the % purity of this naoh sample?.

we have to select the terms that are associated with communication between neurons.

synapse is the gap between two neurons that is there to transmit the signal.

from one neuron to other neuron the signals transmit through neurotransmitter which is a chemical and finally after reaching it becomes the electrical signal

therefore, option 4th is correct that is: synapse,electrical signals and neurotransmitter.
