Why is it possible to monitor the reaction between crystal violet and sodium hydroixde with a spectrometer. Using the word collison theroy in the answer.

Solutions

Expert Solution

The kinetics of the reaction between crystal violet and NaOH can be monitored by a spectrophotometer by observing the decrease in absorbance of crystal violet with time. A Spectrophotometer colorimeter is be used to monitor the crystal violet concentration as a function of time. The reactant and product structures and the reaction stoichiometry are shown in Figure 1 below.

This reaction can be represented as:

CV⁺ + OH^- → CVOH
purple colourless

The kinetics of this reaction can be monitored with a spectrophotometer by observing the decrease in absorbance of crystal violet with time. The rate law form is: rate of disappearance of CV = rate of appearance of CVOH = k [CV]^x [OH^- ] ^y
[OH-] can be treated as a constant and rate Equation can be written as , Rate = k'[CV] ^x
