# Conductivity — AP Chem Definition & Exam Guide

## Definition

Conductivity refers to the ability of a substance or solution to conduct electricity. It is a measure of how well electric current can flow through it.

## Review

### Related Terms

- Electrolytes: Substances that dissolve in water and produce ions, which increase conductivity.
- Insulators: Substances that do not allow electric current to flow through them, resulting in low conductivity.
- Salts: Ionic compounds formed by the reaction between an acid and a base, they dissociate into ions when dissolved in water, increasing conductivity.
