Planning Aim: To investigate the rate of reaction between Sulphur Thiosulphate and Hydrochloric Acid. This experiment is primarily based on chemical reactions and what affects the rate of these reactions. To grasp the idea of the experiment, one must first understand the fundamental knowledge behind chemical reactions. The features of a chemical reaction are summarised below: * One or more new substances are produced. In many cases an observable change is apparent, for example a colour change or a gas is produced. * An apparent change in mass may also occur. The change is usually due to gas being given off. * An energy change is almost always involved. In most cases energy is released and the surroundings become warmer. In some cases energy is absorbed from the surroundings and so the surroundings become cooler. For a chemical reaction to occur, the reacting particles (atoms, molecules and ions) must collide. There must be enough energy involved in...
