According to previous replies from the YZHMS Super Edition Assistant, it is believed that a testing and analysis should be conducted first. Because there’s too much red-colored substance… Red and purple aren’t that different from each other… Last edited by haining on 2009-3-6 15:47]
After filtering the solution through filter paper, it was found that the filtrate was clear and colorless, while all colored substances remained on the filter paper. This shows that it is the colloids in the solution that get retained, agreeing with the opinion above.
