The Effects of Acid Rain on Statues :: Acid Rain Chemical Reactions Essays

The effect of Acid Rain on StatuesIntroduction------------During this investigation, I will utilisation dilute hydrochloric mordant as the dose come down and crushed calcium carbonate as the chemical of thestatues. hence I will magazine how long it steers for the limestone powderiseto react until there is no more left(a) when the acid is added to it. Rain contains acid naturally as it collects carbon dioxide from the manner and makes carbonic acid. Rain normally has a pH of about 5.5 itis sparingly acidic due to the carbon dioxide dissolved in it. It is astronger acid if gases like sulphur dioxide and nitrogen oxides escapeinto the air from the burning fogey fuels, beca economic consumption they are dissolvedby the rain and produce sulphuric and nitrous acids that does moredamage in a faster time. Acid rain reacts with statues and buildingsthat contain calcium carbonate and form carbon dioxide and irrigate. The dilute hydrochloric acid in this investigation will have the sameeffect on the limestone as the acid rain on the statues. Yet, theonly difference is that in nature, the acid rain reacted with thestatue as a whole body, which engineers approximately nose candy years tocorrode the object, whereas the hydrochloric acid in thisinvestigation will take only few seconds to react with the limestonepowder. deviseningAim---The aim of my experimentation is to investigate if the speed at which thelimestones are dissolved is changed by how strong the acid is.EquipmentTo do my experiment, I will need beakers, a root spoon, a stop clock,limestone powders, stirring rod, measuring cylinders and an electronicbalance for powdersPlanFor this experiment, I will use 30mls of the acid each time and 1gm of powder calcium carbonate. The concentration of the acid will bechanged by adding water supply and less acid each time. First, I will use a paper spoon to spoon out the limestone powder andweigh it on the electronic balance. Next, take out the excess powderu ntil the weight is 1gm. Then use two measuring cylinders, with eachmeasuring the make out of water and dilute hydrochloric acid that shouldbe added, e.g. when there is 30mls of acid, 0mls of water will beadded when there is 25mls of acid, 5mls of water will be added, andso on. The total amount will always be 30mls. Afterwards, I will pourthe powder into a beaker that contain correct amount of acid in it anduse a stop clock to time how long it will take for the powder todisappear. A stirring rod will be employ so that no lumps would form.
