Modelling the Differences Between Strong, Weak, Concentrated, and Dilute Acids and Bases
Dot-Point 5: construct models and/or animations to communicate the differences between strong, weak, concentrated and dilute acids and bases (ACSCH099)
When working with acids and bases, it’s crucial to distinguish between strength and concentration:
Strength: Refers to how much the acid or base ionizes in water.
Strong acids/bases: Fully ionize (e.g., HCl → H⁺ + Cl⁻).
Weak acids/bases: Partially ionize (e.g., CH₃COOH ⇌ H⁺ + CH₃COO⁻).
Concentration: Refers to the amount of acid or base dissolved in a given volume.
Concentrated: High number of molecules in solution.
Dilute: Low number of molecules in solution.
The diagram you make should ideally look something like this:
NOTE: Do not use colour in your exam. Use letters, shaded/unshaded dots or different shapes (circles, triangles, squares etc.)!!The dissociation of acids and bases in water can be represented with ionic equations.
