Question

A scientist’s work is never finished. after proving or disproving a hypothesis, it’s common for scientists to conduct additional experiments to further advance their hypothesis or expand their findings. using the same materials, what additional experiments could you perform to further develop or enhance your conclusion of how acids affect limestone?

Answer 1

A scientist’s work is never finished. after proving or disproving a hypothesis, it’s common for scientists to conduct additional experiments to further advance their hypothesis or expand their findings. using the same materials our wok is to make conclusions in the world of chemistry , to expand our knowledge or to develop the conclusion.

Therefore, when sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves.

Also, we now have a conclusion, Limestones are sensitive to acid.

Common chemical reaction of acid affecting limestone,

H2SO4 + CaCO3 ⇄ H20 + CaSO4 + CO2,

CaSO4 (Calcium Sulphate) is soluble in water, and hence the reaction releases CO2 (Carbon dioxide) in the atmosphere, which then affect limestone.
