Question

Potassium chloride conducts electricity in _____ state.

Answer 1

Hint: In order to answer this question, to know the type of state in which the potassium chloride can conduct electricity, we will explain the reason and the type of state in which it can conduct electricity and also we will explain the situation in which it can’t conduct electricity.

Complete answer:
Potassium chloride is an electrovalent compound and conducts electricity in the molten or aqueous state because in the fused state or in aqueous solution, the electrostatic powers of attraction are weaker. Hydrogen chloride, for example, is a polar covalent compound that ionises in solution and can act as an electrolyte.
Charge particles such as electrons and ions must be able to travel freely within a material in order for it to conduct electricity. Potassium chloride (like many other ionic compounds) has fixed ions in its solid state, making it immobile and unable to conduct electricity.
Potassium is an excellent electrical conductor. Since it has four shells and a single electron in the outermost shell, it has a larger atomic radius. As a result, it has a lower ionisation energy and has a higher proportion of free electrons, making it a strong conductor of electricity. Potassium is derived from igneous rocks and mineral sediments.

Note:
Now, a question arises here that why potassium chloride doesn’t conduct electricity in its solid state? So, it doesn’t conduct electricity in its solid state because of strong cohesive forces that make its ions immobile.
