BIOLOGY SC1 ASSESSMENT DOES DOUBLING THE STRENGTH OF AMMONIA DOUBLE THE RATE OF ITS DIFFUSION? PLANNING In this investigation I am trying to find out if doubling the strength of ammonia doubles the rate of its diffusion. There are a few factors that may have an effect on the results of this investigation. For example, the size of the test tube, the distances between each piece of litmus paper and the amount of ammonia on the wool. The longer or wider the test tube the more time it will take for the ammonia molecules to diffuse along the tube which would increase the time on the results table. A similar principle would apply to the distance between litmus papers. The ammonia is most likely to reach the litmus paper closest to it first and then to the second as it will take more time for the ammonia molecules to diffuse across the tube....
