Question

Electrolyte or Non-electrolyte Questions?
1. Why do substances need to be dissolved in water to form electrolytes

2. Natalie decides to take a bath. she fills the tub, sets her radio on the side of the tub, and gets in. If the radio falls in the tub, would it make a difference if she was bathing in distilled (pure) water or tap water? Why or why not?

Answer 1

1. Because when they are solid, they cannot conduct electricity.

Answer 2

1. It's simple, when they are solid, the ions can't move because they are 'stuck', the substance must be molten or dissolved in water in order for the electrons to move around.
The electricity is something very simple-moving electrons form one place to another.

Answer 3

2. The Distilled water is basically 'distilled', that means that there is a small amount of ions in it. The lower amount of ions, the lower the conductivity. It will conduct electricity, but it will have a lot of resistance.
The tap water has a lot of ions in it, that makes it easy for the electricity to pass through it.
Let's put it that way, the tiny ions carry the electric charge if there aren't any ions, who would carry the electric charge? The tap water is a better conductor than the distilled water.
