Qualitative Kinetics - Crystal Violet/Hydroxide Ion Reaction

Crystal Violet/Hydroxide Ion Reaction



CV+ + OH- CVOH

NOTE: This is a symbolic form for the equation.

In each of the experiments below 5 mls of 1 x 10-5 M crystal violet is placed in a test tube and 5 mls of NaOH added. The first test tube in each set of pictures contains only crystal violet. The other test tubes contain crystal violet and the NaOH solution (which is colorless). The numbers under the test tubes indicate the number of elapsed seconds.
