Answer 2

When an ionic compound dissolves in water, it increases the water's ability to conduct electricity. This is a characteristic of all salts. its in apex

--------------------------------------------------------------------

Because sodium chloride is the product of a neutralization reaction: a reaction between an acid and a base. Also is an ionic compound as many other salts.
