Introduction: for this experiment/investigation I want to find out how long it takes for two different solutions to react togeather, these are; Hydrochloric acid and sodium Thiosulphate. I will change the concentration of the sodium thiosulphate to see whether this affects the rate of the reaction. Other things that may affect the rate of a reaction are temperature, catalysts, size of bits and surface area, but were just testing the concentration area. A reaction goes quicker if the temperature rises. This is because of the increase in kinetic energy, which enables the particles to collide more quickly. A powdered substance reacts more quickly than one with larger bits. This is because the powder has much bigger surface area, so more reacting particles come into contact. Concentration is the number of particles there are in a given volume; this is measured in Molarity. I will use 0.15 M of sodium thiosulphate. For these two chemicals to react...
