Electrolytes and Dissociation (Video Notes Review)

Flashcards covering electrolytes, dissociation, dissolution, and examples of strong/weak electrolytes and non-electrolytes based on the lecture notes.

What is a strong electrolyte?

A substance that fully dissociates into ions in water; examples include strong acids, strong bases, and salts.

What are examples of strong electrolytes?

Strong acids (e.g., HCl), strong bases (e.g., NaOH, KOH), and salts (e.g., NaCl, KBr, MgCl2) that fully dissociate in water.

What is a weak electrolyte?

A substance that partially dissociates into ions in solution, conducts electricity but not very well.

What is a non-electrolyte?

A substance that dissolves in water but does not produce ions; remains as intact molecules and does not conduct electricity.

What is a weak acid example?

Acetic acid (CH3COOH) is a common example.

Non-electrolyte examples

Sugars (glucose, sucrose), alcohols (ethanol, menthol); many organic compounds that do not ionize in water.

Dissociation

The act of a chemical being separated into ions in solution.

Dissolution

The act of a chemical being incorporated into a solvent to form a solution.

Are covalent compounds strong electrolytes?

Covalent compounds can be strong electrolytes only if they ionize completely; otherwise they are weak electrolytes or non-electrolytes.

Strong acid example

Hydrochloric acid (HCl) is a strong acid that fully dissociates in water.

Weak base example

Ammonia (NH3) is a common weak base that partially dissociates in water.

What is an electrolyte?

A substance that dissociates into ions in solution and conducts electricity.

Dissociation vs dissolution difference

Dissociation is the separation into ions; dissolution is the incorporation into a solvent to form a solution.
