The results were checked by looking at the color of the solution. Total coliform was detected if the solution turned yellow and the gel rose to the surface which happened with the control sample, the black tablet no motor sample, and the tablet with motor sample. The liquid no motor sample turned yellow but the gel did not rise which meant the ph changed but no e.coli formed in the sample. Total coliform was not detected and there was no ph change in the liquid bleach with motor samples taken after both 3 and 10 minutes because their colors changed to red and the gel stayed at the bottom of the test tube.
