Year 7 Science

7WR and 7CT looked at displacement reaction this week. Mr Spain used aluminium foil in a mixture of copper chloride and hydrochloric acid and lit the hydrogen gas produced.

Due to the copper displacement in this reaction the flame has a lovely blue -green hue, just like the Northern lights, followed by a pop as the hydrogen gas reacts with oxygen.

Key Stage 4 Science

Dr Gonzalez has introduced a spectacular, exothermic reaction to 11W5 and 10CB, as a recap to the catalysis topic in chemistry. Potassium permanganate was sprinkled over a mixture of peroxide and ethanol to create these series of loud but harmless bangs.
