This experiment uses plant pigments and tests them to see if they are good pH indicators. The hypothesis was that if a carrots pigment were removed and tested with a range of pH solutions, then it would prove to be a good pH indicator. The null hypothesis is that the carrot pigment will remain unchanged when tested with the various pH solutions, therefore indicating that the carrot’s pigments are not good pH indicators. Isopropyl alcohol was used to extract pigment from two grams of ground up carrot. The pigment was yellow. Then, using 14 numbered test tubes; 9ml of distilled water was put in all test tubes except one and 14. In number one, 10ml of HCl was put in, and 10 ml of NaOH was put in number 14. Then a serial dilution was performed going from one to six and then 14 to 8. This provided pH solutions ranging from a pH of one to a pH of 14. Then a spot plate was numbered and a few drops from each numbered test tube were put in the corresponding spot on the spot plate. Next, a few drops of the carrot pigment were placed in each spot of the spot plate. The color change was then observed. This experiment supported the null hypothesis because the experiment showed that a carrot is not a good pH indicator. All of the solutions in each spot plate remained yellow.
