Short explanation
Distinguish an insoluble base from a soluble alkali when describing oxides. This objective belongs to Metal oxides within Reactivity of metals for AQA GCSE Chemistry 8462. A strong answer should use alkali accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
