DISCOVERIES IN CHEMISTRY AND THEIR IMPACTS ON PUBLIC LIFE INTRODUCTION Every single day, without even realising it, we use so many things that are brought to us by the discoveries and advances in chemistry. Many of these things we take for granted, and don 't even bother to question how it got there, why it is there, and how it works. Chemistry makes up everything in our lives, from the air that we breathe, to the plastic on the keyboard I 'm typing on now, and a in depth study of some of the

He continued his higher level of education at Massachusetts Institute of Technology. The inventor and pioneer in the field of organic chemistry later then set up a laboratory in Montclair, New Jersey where he continued

had a pH of 7.35, indicating an almost neutral profile. The above mine sample had a conductivity of 2200 µS/cm, whereas the below mine sample had a conductivity of 7500 µS/cm. This suggests that there are a significantly greater number of ions in solution in below mine water than above mine water. The below mine sample also had greater water hardness, with a calcium ion concentration of 5183.29 mg/L, compared with the above mine sample’s hardness of only 115.02 mg/L. The above mine water mostly exhibited

in three equivalents of hydrochloric acid and one equivalent of sodium nitrite in aqueous solution followed by two equivalents of sodium acetate. Reaction: Procedure: 1. In a 100 mL conical flask place 20 mL of water, 5 mL conc. HCl and 3.5 g aniline. 2. Shake vigorously and add about 15 g crushed ice. 3. In a test tube dissolve 1.3 g sodium nitrite in 3 mL water. 4. Add this sodium nitrite solution to above reaction mixture with constant shaking drop by drop. 5. Allow to stand with frequent

concentration. Heavy metals are characteristic parts of the Earth's covering. They can't be debased or destroyed. To a little degree they enter our body by means of drinking water, food and air. As follow components, some substantial metals (e.g. copper, selenium, zinc) are crucial to look after the metabolism of the human body. At higher concentrations they can accelerate poisoning. Devastating poisoning of metals arise from drinking-water pollution (e.g. lead channels), high surrounding air fixations

20 volumes of oxygen. A 20 "volume" concentration of hydrogen peroxide is equivalent to 1.67 mol/dm3 (Molar solution) or about 6%.Hydrogen peroxide available at drug stores is three percent solution. In such small concentrations, it is less stable, and decomposes faster. It is usually stabilized with acetanilide, a substance which has toxic side effects in significant amounts. Buffer solution is used in this experiment as to keep the pH at a

between the weight of the test tube and the test tube with blended potato is recorded as the weight of the blended potato. 5. The test tube then was added with 5 cm 3 of 6.5 buffer solution by using 5cm 3 measuring cylinder. 6. The test tube was then swirled in order to mix the blended potato and buffer solution well. 7. A beaker and an upside down 50 ml measuring cylinder inside the beaker was set up. Both beaker and measuring cylinder are filled with water. It is sure that there is

Introduction. A swimming pool is an artificially enclosed body of water that is used for either leisure pursuits or to be enjoyed and utilised in aquatic sports. Pools range from all shapes and sizes and also varied use, for example, they could be private, public and competitive. Swimming pools are also built either above or below ground varying in the material they are built with, whether it is concrete, metal, fibreglass and or plastic. The key to operating a pool is keeping it clean and chemically

We need a balanced diet full of essential vitamins and minerals to help our body function at the optimum level, our bodies cannot create vitamins and minerals and therefore we have to get them from the food we eat. They are essential in making proteins and helping cells to grow and repair. There are 2 main types of essential vitamins, water-soluble and lipid-soluble. Water-soluble vitamins cannot be stored in the body, so we have to eat them every day, as they are excreted through urine. They are
