Chapter 10.14, Problem 3QQ

Interpretation Introduction

Interpretation:

Correct statement regarding the conduction of electricity by an aqueous solution has to be identified form the given options.

Concept-Introduction:

Electrolyte: It is a substance that is able to conduct electricity in its aqueous solution. This is due to presence of charged particles (ions) in the aqueous solution.

There are two types of electrolytes,

• Strong electrolyte: These are substances that can completely or almost completely dissociates to their corresponding ions in the aqueous solution. Strong electrolytes give solutions that are strongly conducting. Strong electrolyte includes all strong bases and strong acids and all soluble salts.
• Weak electrolyte: These are substances that dissociates incompletely into corresponding ion in aqueous solution. Weak electrolytes give solutions that are intermediate between those having strong electrolytes and those having nonelectrolytes in their ability to conduct an electric current. Weak electrolytes include weak acids and weak bases.

Nonelectrolyte: It is a substance that does not conduct electricity in its aqueous solution. Glucose, table sugar are examples for nonelectrolytes.
