Question

why do we prefer to store material and chemicals in plastic bottke rather than the iron or tge glass bottle?

Answer 1

because iron is a metal and if we will store chemicals they will react with them. thats why we store chemicals in plastic bottles.

Answer 2

Fe is a metal which is acidic in nature which ionizes with H2O ion to form Fe2O3. Iron reacts with material .So we prefer to store material in plastic bottle.But we don't store all chemicals in plastic bottles as some are most reactive and are also exothermic.
