Final answer:
Strong electrolytes and weak electrolytes differ in their degree of ionization in solution. Strong electrolytes ionize completely, while weak electrolytes only partially ionize.
Step-by-step explanation:
Strong electrolytes and weak electrolytes are substances that conduct electricity when dissolved in water. The main difference between them lies in their degree of ionization. A strong electrolyte ionizes completely in solution, producing a high concentration of ions, while a weak electrolyte only partially ionizes, resulting in a lower concentration of ions.
For example, hydrochloric acid (HCl) is a strong acid and ionizes fully in water, releasing a high concentration of hydrogen ions (H+) and chloride ions (Cl-). The equation for its ionization is:
HCl(l) → H+(aq) + Cl-(aq)
On the other hand, acetic acid (CH3COOH) is a weak acid and only partially ionizes in water. The equation for its ionization is:
CH3COOH(l) → H+(aq) + CH3COO-(aq)
