BRAINCAKETypes of Reaction
Revision notes for Types of Reaction in Edexcel Chemistry (8CH0). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- Metal Displacement ReactionsWhen a metal reacts with a compound of a different metal, the more reactive metal displaces the less reactive metal from its compound.
- Metal Displacement Reactions in the Solid StateWhen a metal reacts with a compound of a different metal, the more reactive metal displaces the less reactive metal from its compound.
- Halogen Displacement ReactionsHalogen displacement reactions are redox reactions where the more reactive halogen displaces the less reactive halide from its salt in solution.
- Precipitation ReactionsTest for carbon dioxide - if the gas given off is bubbled through limewater if it turns cloudy (white precipitate is formed) the gas is identified…
- Reactions of Acids with Metalsacid + metal → salt + hydrogen This is a displacement reaction and is also a redox reaction.
- Reactions of Acids with Insoluble BasesMany metal oxides are insoluble bases.
- Reactions of Acids with alkalisAn alkali is a substance that releases hydroxide ions OH- in solution.
- Reactions of Acids with Carbonates and Hydrogen CarbonatesCarbonates contain the CO32- ion. acid + carbonate → salt + water + carbon dioxide.
