Investigating the effect of concentration on the reaction of propanone and iodine. Formula The equation for the reaction is: - CH3CO.CH3 CH3.CO.CH2I + HI Prediction I predict that increasing the concentration of the propanone increases the rate at which reaction with iodine (I2) takes place, because the density of particles in more concentrated solutions is greater, the chances of collision between propanone particles and iodine particles increases, the chance of reaction also increases. Furthermore if the concentration doubles I predict that the rate of reaction will double because the density of the particles doubles, doubling the chance of collision. Predicted graph Fair test To ensure the experiment is a fair test I must control the variables these are: -> The volumes of each solution, these will be carefully measured from burettes, this will ensure accurate measuring> The amount of I2 will be kept constant, a white tile will be used and when the tile is as...
