Under What Conditions Can Potassium Bromide Conduct Electricity?

Potassium bromide will conduct electricity, after it is melted. Heat and liquid both release the ions in potassium bromide to permit free movement of particles, which allows it to become conductive, according to Everything Science, a site focused on spreading scientific knowledge.

Potassium bromide in its solid form contains ions, which are charged atoms. However, the ions are bound so tightly in the solid form of potassium bromide that electricity cannot flow between them. Once it is melted, though the ions are free to move and electricity can be passed between them. Through the heating process, the melted potassium bromide becomes an ionic liquid. If solid potassium bromide is dissolved, for example in water, the resulting release of ions allows it to conduct electricity.
