is conductivity a physical or chemical property

Electrical conductivity is a physical property. A chemical property involves a change that occurs. However, when electricity passes through an object or substance, no change occurs.

if i'm testing conductivity of different salts?

so it is a physics project

Conductivity is a physical property. It refers to the ability of a substance to conduct electrical current.

To determine if a property is physical or chemical, we can consider whether it describes the behavior or characteristics of a substance without any changes to its chemical composition. In the case of conductivity, it can be measured and defined without altering the chemical composition of the substance.

To determine the conductivity of a substance, you can perform an experiment using a conductivity meter, which measures the flow of electric current through a material. Simply connect the conductivity meter to a sample of the substance and observe the reading. A high reading would indicate good conductivity, while a low reading would indicate poor conductivity.

It's important to note that although conductivity is a physical property, it can be influenced by the chemical composition of the substance. For example, ionic compounds, which dissociate into ions in water, tend to have higher conductivity compared to covalent compounds.

same goes for salts
