Question

Explain reactivity series and write its one use.

Hint:

Metals higher in the reactivity series displace metals lower in the series from their Solution.

Answer 1

The Reactivity Series is a list of metals arranged in decreasing order of their reactivity. Highly reactive metals like potassium (K) and sodium (Na) are at the top, while less reactive metals like gold (Au) and silver (Ag) are at the bottom.
Use: It helps in predicting displacement reactions where a more reactive metal can displace a less reactive metal from its compound.
