Reactivity series outcomes5 objectives
- List the sequence of metals in the reactivity series, which includes potassium, sodium, calcium, magnesium, aluminium, carbon, zinc, iron, hydrogen, copper, silver, and gold.
- Explain the reactions of potassium, sodium, and calcium with cold water; magnesium with steam; and the reactions of magnesium, zinc, iron, copper, silver, and gold with dilute hydrochloric acid, relating these reactions to their positions in the reactivity series.
- Infer the reactivity order of metals based on a provided set of experimental data.
- Discuss the relative reactivities of metals by examining their ability to form positive ions and their displacement reactions with the aqueous ions of magnesium, zinc, iron, copper, and silver.
- Clarify why aluminium appears unreactive by discussing the protective layer formed by its oxide.
