Acidity Research By Kyan Mulji 9s Table of content What is acidity and some of its uses? Before I can define acidity I would like to define an acid. An acid is a word originated from an latin word acere meaning sour in English. The general characteristics of acids are 1. They taste sour. 2. They are corrosive to metals 3. They turn litmus paper red 4. They have a PH of 1 to 6. 5. Usually gases or liquids 6. Frequently feel sticky 7. Acids nuetralise bases to form slats and water 8. They react with active metals to form hydrogen 9. React with carbonates to produce a salt, water and carbon dioxide 10. Turn methyl orange to red. The ph scale can be used to determine how strong an acid is. One meaning the acid is very strong and six meaning the acid is very weak. Some examples of acids are in the table below Formula Name Strong? HCl hydrochloric acid yes HBr hydrobromic acid yes HI hydroiodic acid yes HF hydrofluoric acid no HNO3 nitric acid yes H2SO4 sulfuric acid yes H3PO4 phosphoric acid no CH3COOH acetic acid no The table above shows that most of the acids are very strong. Acidity can be defined as the amount of acid found in a certain mixture for example in water. Acids in industrys Acids such as nitric acid, sulfuric acid, phosphoric acid have countless uses in industrys. Soe acids like acetic acid or the phosphoric acid in soft drinks are sold as consumer products. Other acids are used on synthesis of dyes, fertilizers, explosives, and many other chemical substances that are essential in our lives Fertilizers Fertilizers are essential to modern industrial agriculture. Two of the most important plant nutrients are nitrogen and phosphorus. Nitric acid, phosphoric acid, ... ... middle of paper ... ... that involves crushed limestone being mixed with water. This forms a slurry. It is then sparayed into the area containing sulfur dioxide. This reacts to form a aqueos slurry of calcium sulphate. Compressed air is then blown into this slurry. This oxididses the calcium sulfite to form calcium sulphate. The product is treated to remove excess waterand is disposed in land fills. Another system is called the spray dry system. A slurry of alkali is njected into the flue gases. The heat in the flue gases causes water to evaporate. The sulfur dioxide reacts with the drying alkali solution to form a solidi reaction product. There is no waste water from this process. Seawater scrubbing system – This is using the natural alkalinity of sea water ti aboarb acidic gases. The flue gases are trapped in a abosrbtion tower. This is where they flow aginst a current of sea water
