1 Lesson 25 Why do some liquids conduct electricity?

2 Solutions of acids, bases, and salts conduct electricity. Solids of acids, bases and salts do not. Neither do liquids like alcohol, sugar water, distilled water and glycerine.

3 Why do solutions of acids, bases and salts conduct electricity? Matter is made of atoms. Sometimes atoms join together to form molecules.

4 Most atoms and molecules have no electrical charge. They are neutral. The atoms of substances that are not acids, bases, or salts stay neutral, even when they dissolve.

5 When an acid, base, or salt dissolves, its atoms do not stay together. The atoms unlock. Whey they unlock, they do not stay neutral.

6 They take on electrical charges. Some take on a positive charge. (+) Some a negative charge. (-) Charged atoms are called ions.

7 Ions let electricity pass through a solution. Solutions that have ions are called electrolytes. Liquid acids, bases, and salts form ions. That is why they conduct electricity.

8 Liquids such as alcohol, sugar water, distilled water, and glycerin do not form ions. That is why they do not conduct electricity. They are non-electrolytes.
