Conductivity is a measure of a material's ability to conduct an electric current. In the context of chemistry, conductivity often refers to the ability of a solution to conduct electricity.
Factors Affecting Conductivity
Several factors can affect the conductivity of a solution:
Ionic Strength: Solutions with higher ionic strength tend to have higher conductivity.
Measuring Conductivity
Conductivity is typically measured using a device called a conductivity meter, which measures the ability of a solution to conduct an electric current. The unit of conductivity is often reported in siemens per meter (S/m) or microsiemens per centimeter (μS/cm).
Applications of Conductivity
Conductivity measurements are important in various fields, including:
Environmental Monitoring: Conductivity measurements can help assess the health of natural water bodies.
Industrial Processes: Monitoring the conductivity of solutions is crucial in various industrial processes, such as in the production of chemicals.
Quality Control: Conductivity measurements can be used to ensure the proper concentration of ions in solutions during manufacturing processes.
Study Guide
To understand conductivity better, consider focusing on the following key points:
Understand the concept of electrical conductivity and how it applies to solutions.
Use mathematics and computational thinking to express the concentrations of solutions quantitatively using molarity.
Use the concept of pH as a model to predict the relative properties of strong, weak, concentrated, and dilute acids and bases (e.g., Arrhenius and Brønsted-Lowry acids and bases).
