How do you clean up strong acid spillages eg sulphuric acid?

Answer 1

Initially , water, which will dilute the acid.

You can add powdered chalk , calcium carbonate'. This will neutralise the acid to its salt.

e.g. H2SO4 + CaCO3(chalk) = CaSO4(salt) + H2O +CO2

Note all the acid has gone.

Answer 2

Strong acids like Sulphuric acid are corrosive and have affinity for moisture with the hydrogen ion displaced to give a pungent odor.Acids react with bases such as hydroxide ion and Ammonia to give salt and neutralise the acid.Alkalis like sodium hydroxide can be used to neutralise the acid and clean up the spillage.
