Multiple Choice

Which chemical is very corrosive and should be stored in glass, plastic, or rubber lined containers?

Storing corrosive chemicals safely hinges on choosing container materials that resist chemical attack. Ferric chloride solutions are highly corrosive to many metals, so using unlined metal tanks would quickly lead to container degradation, leaks, and safety hazards. Glass is chemically inert, plastics like certain high‑grade polymers offer strong resistance, and rubber linings provide a protective barrier on metal surfaces. These options help prevent the ferric chloride from reacting with the container itself, keeping storage safe and stable. The other substances in the list are either solids or not as aggressively corrosive toward common storage materials, so they don’t require the same level of lined containment.
