    ACID / BASE BUFFER SYSTEMS Abstract A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solutions (Bicarbonate/carbonic acid)‚ Lake water and distilled water were obtained to compare their buffering behaviours when mixed both with an acid and a base. The results showed buffering capacities for

    endothermic reaction happened everywhere around us. Basically exothermic and endothermic reaction is transfer energy to the surroundings and take in energy from the surroundings (BBC GCSE bitesize). If the reaction forward ,then is exothermic.If the reaction is the backwards ‚then is endothermic. When a reaction take place‚ the energy started to transfer from different object to the surroundings or take away energy from the surroundings. When temperature started to change. Exothermic Reaction An exothermic

    Acid rain‚ or more accurately acid precipitation‚ is the term used for describing rainfall with a pH level lower than 5.6. This type of pollution is a matter of great debate currently due to the potential of its causing environmental damages all across the world. For the last decade or so acid rain has caused destruction to hundreds of lakes and streams in many parts of the world‚ including the US‚ Canada‚ and Europe. Acid rain forms due to the oxides of sulfite and nitrogen combining with the moisture

    X Experiment Introduction I am going to investigate the rate of reaction between sodium thiosulphate (thio) and hydrochloric acid. Hydrochloric Acid + Sodium Thiosulphate "" sodium chloride + water + sulphur The reactants are both colourless‚ but one of the products‚ sulphur‚ is yellow‚ so we can use this fact to follow the rates of reaction. I am going to investigate how the concentration of the acid effects the speed of the reaction. Apparatus 1 small measuring cylinder 1 large measuring

    I. Introduction The purpose of this experiment is to determine the pH values of acids‚ bases‚ and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution‚ or containing an atom that can accept a pair of electrons from a base (McKinley‚ Dean O’Loughlin‚ & Stouter Bidle‚ 2016). Bases are water-soluble
