Container for keeping strong acids are made of

Answer 1

Container for keeping strong acids are made of lead.

Answer 2

Answer:

Container for keeping strong acids is made up of lead because of its anti-corrosive property and strong resistance to corrosive liquids.

Solution:

Strong acids like hydrochloric or sulphuric acid forms an insoluble protective coating of lead chloride or lead sulphate respectively on the metallic surface of the container to prevent any further reaction or dissolution of lead with the acid. This is the reason for lead being used in storage batteries where sulphuric acid remains the electrolyte Concentrated acids do not dissolve lead in the lead containers up to 2000C; however, higher temperatures will lead to the dissolution of the metal.
