Addition of hydrochloric acid to crystal violet means lowering the PH of crystal violet by increasing the concentration of … WebWe created a reaction between crystal violet and sodium hydroxide (CV+ + OH- = CVOH). We performed this reaction twice to find the different rates of reaction (m and n) by observing the absorbance at max wavelength over time. With data, we found out the rate constants k1 and k2 and the half life of the reaction.
