Topics

• Metals are arranged in order of how readily they react: the reactivity series, potassium at the top, gold at the bottom.
• K Na Ca Mg Al Zn Fe Pb H Cu Hg Ag Au: hydrogen is placed in the series as a reference point.
• Potassium and sodium react violently with cold water, giving hydrogen that catches fire at once.
• Magnesium reacts with hot water; aluminium, zinc and iron react only with steam.
• Metals above hydrogen displace it from dilute acids: magnesium fizzes fastest, then zinc, then iron slowly.
• Copper, mercury, silver and gold lie below hydrogen, so they do not react with dilute acids at all.
• A more reactive metal displaces a less reactive one from its salt solution: Zn + CuSO₄ → ZnSO₄ + Cu.
• The zinc strip turns brown with copper and the blue solution goes colourless as the Cu²⁺ ions leave it.
