Chemicals that conduct electricity when mixed with water are called electrolytes.

Chemicals that conduct electricity when mixed with water are called electrolytes. Electrolytes are substances that dissociate into ions when dissolved in water, allowing the flow of electric current through the solution. Some common examples of electrolytes include salts, acids, and bases.

To determine if a chemical is an electrolyte, you can follow these steps:

1. Check if the substance is soluble in water: Electrolytes must be able to dissolve in water to form ions. So, if a substance is insoluble in water, it is unlikely to be an electrolyte.

2. Determine if the substance can dissociate into ions: Electrolytes are made up of ionic compounds or substances that can form ions when dissolved in water. For example, table salt (sodium chloride, NaCl) dissociates into sodium ions (Na+) and chloride ions (Cl-) when dissolved in water.

3. Test for conductivity: The final step is to test whether the solution of the chemical conducts electricity. This can be done by using a conductivity tester or a simple circuit with a light bulb or a voltmeter. If the solution allows the flow of electric current, it indicates the presence of electrolytes.

Remember that not all substances will conduct electricity when mixed with water. Non-electrolytes, such as sugar or alcohol, do not dissociate into ions and therefore do not conduct electricity.
