Understanding the differences between strong and weak acids and bases can be tough for Year 8 students. Let’s break it down:

Dissociation:

• Strong acids and bases completely break apart in water.
  (Examples: hydrochloric acid and sodium hydroxide)
• Weak acids and bases only break apart a little bit.
  (Examples: acetic acid and ammonia)

pH Levels:

• Strong acids have a pH close to 0.
  Weak acids have a pH from 4 to 6.
• Strong bases have a pH between 12 and 14.
  Weak bases have a pH from 8 to 10.

To help students understand these concepts better, hands-on experiments and visual aids can make things easier to grasp.
