    ACID RAIN Acidified particulate matter in the atmosphere that is deposited by precipitation on to a surface‚ often eroding the surface away. This precipitation generally has a pH less than 5and some times much lower depending upon the concentration of acidic components. Acidic deposition principally by the pollutant gases such as sulphur dioxide (so2) and the nitrogen oxides cause acidic deposition. The burning of fossil fuels‚ such as coal‚ forms Sulphur dioxide. that contain high quantities of

    air or be left in the ash of the burnt battery. By draining and neutralising acid from the batteries and recycling them our problem is solved. The one world factors I shall be looking at this from is environment and economic. By: www.leadbatteryuniversity.uk Batteries must always be drained before they enter the recycling process. They should only be drained to a purpose built effluent treatment plant so that the acid can be treated and neutralized. Next the batteries are broken in a hammer mill

    H2SO3 Sulfurous acid is the chemical compound with the formula H2SO3. H2SO3 is a clear‚ colorless liquid with a sulfurous odor. It is a weak acid that is formed when sulfur dioxide is dissolved in water. Sulfurous acid is used as a bleaching and chemical reducing agent that is often used in medicine‚ throat and nasal sprays and skin lotions. Antiseptics‚ anti-fermentative‚ and antizymotics include sulfites that are formed from the acid. This compound is only stable in aqueous solutions‚ and

    Based on calculations #7 made above for solving the molecular weight‚ it was identified that the unknown liquid was Butanoic acid: 88.1g/mol. Since the calculated value was 83.5 g/mol‚ it was assumed that Butanoic acid was the only solute out of all that were listed that shared a similar value. In reference to the results and data used for calculation the molecular weight (MW) for the unknown was successfully proven to match the accepted value of 88.1 g/mol. More specifically‚ this was evident due
