Concept explainers
(a)
Interpretation:
Whether hydrogen chloride is a strong, weak or non-electrolyte is to be determined.
Concept introduction:
The electrolyte is the substance that produces ions when it is dissolved in a polar solvent. It breaks into positively and negatively charged ions that spread uniformly through the solvent. The electrolytic solution, as a whole, is electrically neutral. Sodium chloride, potassium chloride, calcium phosphate are some of the examples of electrolytes.
Strong electrolytes are those electrolytes that completely dissociates into its ions. These have a very high value of electrical conductance. Sodium chloride and potassium chloride are strong electrolytes.
Weak electrolytes are those electrolytes that partially dissociates into its ions. They are poor conductors of electricity. Acetic acid and carbonic acid are weak electrolytes.
Non-electrolytes are the substances that don’t dissociate into ions when they are dissolved in any solvent. They don’t conduct electricity. Urea, benzene, chloroform are non-electrolytes.
