How does the concentration of Sodium Thiosulphate solution affect the rate of its reaction with Hydrochloric acid? Prediction I predict that the higher the concentration of Sodium Thiosulphate solution the quicker the rate of reaction with Hydrochloric acid will be. I think this because the collision theory says that a higher concentration means a larger number of particles in a given volume. If there are more particles, there will be more collisions. More collisions mean a larger number of successful collisions. Therefore the reaction rate will increase. low concentration high concentration Fair test To make my experiment a fair test I will keep the following variables the same: * The temperature of the Sodium Thiosulphate * The total volume of all the liquids when added together * The amount of Hydrochloric acid * The same cross * Always measure the level of liquid at the meniscus * Use the same person to measure out...
