Question

Describe an experiment used to test conduction of electricity in liquids.

Answer 1

When common salt (NaCl) is dissolved in water, it splits into Na+ and Cl– ions. it splits into its component ions. The ions are free to move about in an electrolyte. When a voltage is applied across electrodes placed in the electrolyte, the ions start moving in an orderly fashion.

That is why liquids that have ions, such as acids and solutions of salts and bases, conduct electricity. When an ionic compound melts, it breaks up into ions, which flow when a voltage is applied.
