Titration: ethanoic acid vs sodium hydroxide
The classic weak acid–strong base titration. Standardise 0.1 M ethanoic acid against 0.1 M NaOH using phenolphthalein, and see why the endpoint lands above pH 7.

Flame tests: identifying metal ions
Dip, flame, identify. Use the colours metal ions give a Bunsen flame to identify unknown salts — the same physics that puts colour in fireworks.

Qualitative analysis: identifying the ions in two unknown solids
Two labelled solids, a rack of reagents and no answers. Work through the standard test series, record what you actually see, and name the ions from the evidence.
