The effect of concentration on the rate of reaction Prediction I think that when the concentration of sodium thiosulphate is high then the cross will disappear more quickly. If the concentration of sodium thiosulphate is low then the cross will take longer to disappear. This is because there are more sodium thiosulphate particles. These, when mixed with the water particles, form a 'foggy' solution. The more sodium thiosulphate particles there are the more chance there is that they will collide with the water particles. When they collide then the reaction above takes place and the water goes foggy. This means that the more collisions that take place the quicker the solution turns from transparent to translucent. There are several variables: some that we shall endeavour to keep the same others that we shall be experimenting with. 1) The amount of water. 2) The amount of hydrochloric acid. 3) The amount of sodium thiosulphate. 4) The total...
