Key Questions:

1. What are the products when acids react with metals?
   • Acids react with some metals to produce salts and hydrogen.
2. (HT only) What type of reaction occurs when acids react with metals?
   • (HT) When acids react with metals there is a transfer of electrons so this is a redox reaction.
3. (HT only) In a reaction between copper (II) oxide and carbon, where does each of oxidation and reduction happen?
   • Carbon is oxidised by gaining oxygen to form carbon dioxide. Copper (in CuO) is reduced by losing oxygen to form copper metal. Copper has changed from Cu2 (in CuO) to Cu(s) and so has gained electrons. Cu2 (aq) 2e-(aq) arrow Cu(s)
