[ \text{Mg (s) + 2HCl (aq) → MgCl₂ (aq) + H₂ (g)} ] igcse chemistry past paper
These test your breadth of knowledge. Past papers help you identify "distractor" answers designed to trip you up.
If you are preparing for your IGCSE Chemistry exams (whether through CAIE, Edexcel, or AQA), you’ve likely heard it a thousand times: [ \text{Mg (s) + 2HCl (aq) → MgCl₂
If you’re just starting your revision, don't worry about the clock. Use a past paper alongside your notes. If you hit a question on Electrolysis that you can’t answer, go back to your textbook, study it, and then answer the question. This bridges the gap between learning and applying. Phase 2: The "Timed" Approach
If excess acid is used, what mass of magnesium chloride (MgCl₂) is produced? (Ar: Mg = 24, Cl = 35.5) [2] Use a past paper alongside your notes
