CHM113 Ch4 Electrolytes

Front

What is an electrolyte?

Back

An electrolyte is a substance that dissociates into ions when dissolved in water, allowing the solution to conduct electricity.

Front

What is a strong electrolyte?

Back

A strong electrolyte is a substance that completely dissociates into ions in solution, resulting in high conductivity.

Front

What is a weak electrolyte?

Back

A weak electrolyte is a substance that partially dissociates into ions in solution, resulting in low conductivity.

Front

What is a nonelectrolyte?

Back

A nonelectrolyte is a substance that does not dissociate into ions in solution and does not conduct electricity.

Front

Give an example of a strong electrolyte.

Back

Sodium chloride (NaCl) is a common example of a strong electrolyte.

Front

Give an example of a weak electrolyte.

Back

Acetic acid (CH3COOH) is a common example of a weak electrolyte.

Front

Give an example of a nonelectrolyte.

Back

Glucose (C6H12O6) is a common example of a nonelectrolyte.

Front

What is the role of a solute in a solution?

Back

The solute is the substance that is dissolved in a solvent to form a solution.

Front

What is the role of a solvent in a solution?

Back

The solvent is the substance that dissolves the solute, typically present in greater amount.

Front

What happens to strong electrolytes in water?

Back

Strong electrolytes dissociate completely into ions when dissolved in water.
