Answer:

Explanation:
b) Salt is sodium chloride. ... When the sodium chloride dissolves in water, the sodium atoms and chlorine atoms separate under the influence of the water molecules. They're free to move around in the water as positively and negatively charged ions. This separation of charge allows the solution to conduct electricity.
