Reactivity series
reactivity series
Term | Definition |
---|---|
Reactivity series | Potassium,Sodium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Lead, Hydrogen, Copper, Silver, Gold |
Points about the Reactivity series | displace the less reactive metal, the more reactive the metal, the more stable the compound thus the more difficult it is to extract it from its ore, & less reactive metals are less likely to form compounds |
Stability of Carbonates | most decompose to oxide and carbon dioxide on heating, further down the reactivity series, the more easily the metals’ carbonates decompose |
Stability of Hydroxides | most decompose to oxide and water on heating, further down the series, the easier it breaks down |
Stability of Nitrates | all decompose on heating, potassium/sodium’s break down to form oxygen, other metals’ break down to form oxides and oxygen, further down, the easier it breaks down |
