Answer / sudipta
In case of Dichromate we use it to maintain the pH, otherwise
there is a mixture of Chromate and Dichromate. They donot
absorb at the same wavelength. So we cannot use Lambert-Beer's
Law.
For permanganate use of sulphuric acid is not for this reason
but to maintain the pH as in neutral or alkaline solution
permanganate get hydrolyzed to for manganese dioxide.
