Identification with the color reaction

The results of hemicellulose filtrate titration appear and the first reaction solution of potassium sulfide is added to cadmium forming yellow color and plumbum forming black brown color [33], The final titration is showed by the existence of perfect reaction between hemicelluloses with cadmium and plumbum. Based on the result of the reaction, it appears that there has been a reaction between cadmium and plumbum with hemicellulose as indicated by the specific reaction of cadmium and plumbum in the filtrate titration results. Filtrate titration results indicate sediment that has specific color for cadmium and lead [3]. 

This confirms there has been an ionic bond between the cadmium or plumbum with corn cobs hemicellulose and it forms water-soluble complexes. This is evidenced also by the sediment test titration results showing the results of the same reaction. This means that the deposits were formed in the titration of a precipitate of cadmium hydroxide or plumbum hydroxide.
