Chemistry Research Part 1 Acids Essay

Ethanoic red- vitriolic is non-toxic and is a weak acid 4, essence it will not do each damage to just about surfaces as it does not corrode or bind to other metals, therefore drive out be easily transmitd through washing or rinsing it 2. DisadvantagesEthanoic acidulous is the slowest de-scaler of the three acids, and is therefore the least meative. It also may cause an unpleasant smell, and can have a negative effect on the taste of coffee 6 meaning one would need to make it longer time rinsing and lily-whiteing the machine thoroughly to control that the taste of the coffee is not affected. Citric AcidAdvantagesCitric acid leaves behind zero toxic residues and has just enough acidic minginess to descale without etching or damaging household surfaces in any way and there atomic number 18 no volatile compounds or products that hurt the environment. DisadvantagesBecause citric acid is a weak acid, it wont attain heavy build-up of scale very quickly. It is also a powder t hence it must be dissolved for use. It also works best with hot water meaning there will be higher vital force consumption. Even when used with hot water, citric acid is not as effective at descaling as Sulfamic acid. Sulfamic AcidAdvantagesSulfamic acid is the fastest de-scaler It dissociates into hydroxonium ions more(prenominal) readily in aqueous solution than the others, therefore giving a greater concentration of atoms that are able to react with the calcium in lime scale. It is safe to use because it does not produce chlorine spoil 5, which can be toxic. Sulfamic acid also has a low volatility. DisadvantagesSulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers remove limescaleLimescale forms when hard water is heated above 61C or when it is left to evaporate on surfaces such as taps and showerheads. Hard water is water that contains high quantities of calcium and milligram ions. These hardness minerals, in the form of calcium carbonate and magnesium carbonate, fall down out of hard water to form limescale 1.Therefore, to clean or remove limescale, something needs to dissolve or soften calcium carbonate and/or magnesium carbonate, so it can easily wash away. Acids cause mineral deposits such as rust to oxidise, thereby weakening them and making it mathematical to simply wash them away. Lime scale removers work by chemically reacting with the lime scale to form safe chemicals and ions.Lime scale is calcium Carbonate, and when broken down by strong acids, produces Calcium Chloride, Water and CO2. These are much safer, and can be washed away with water, to remove the CaCl from the area.
