The Cabbage Indicator Experiment My hypothesis for this experiment is if I put an acid or a base in to a neutral then it will change colors. My hypothesis was correct in assuming that it would change colors with different substances or mixtures. If I put an acid or a base in to a neutral then it will change colors. The red cabbage indicator did change colors. Greens for bases and reds and pinks for acids. An alternative hypothesis for this could be “If the red cabbage indicator is purple then adding

3.5 Kinetics of the Alkaline Hydrolysis of Crystal Violet in aqueous solution in the presence of a Cationic and an Anionic Surfactant. 3.5.1 THEORY The alkaline hydrolysis of crystal violet‚ a carbocationicdye(CV+) takes place according to CV+ + OH- ↔ CVOH Where CVOH is the colorless carbinol form of the dye. The kinetics of the reaction can be monitored due to the carbocation form of the dye by measuring the decrease in absorbance at the wavelength corresponding to the absorption maximum(λmax)

The purpose of this experiment is to determine whether peptide bonds are present in various food substances. The color violet will indicate the presence of proteins. The more intense the color is‚ the greater number of peptide bonds there are (Mbuthia‚ 2012). Methods Using the China marker‚ I numbered test tubes 1-5 for identification purposes.

common misconception that ozone holes significantly increased cancer-causing ultra-violet radiation getting through to Earth. "Essentially‚ it’s not very much extra light compared with the amount of ultra-violet that comes through anyway." However‚ the amount of ultra-violet light in New Zealand was two to three times stronger than fair-skinned‚ originally European people were meant to be exposed to. The ultra-violet levels in New Zealand meant our skin cancer rates were much greater than in Europe
