It is not safe to react the most reactive metals (potassium and sodium) with acid in a lab. As you move down the reactivity series (aluminium, zinc, iron) the metals are less reactive, so less ...

The spontaneity of redox reactions is demonstrated using copper, zinc, and silver, and their cations. When solid zinc is placed in Cu2+ solution, the blue color of the solution becomes less intense as ...

Reactivity increases down group 1 but up group 7. Many metals are transition metals. Identifying products - OCR Gateway Laboratory tests are used to detect and identify gases and ions ...
