I'm doing a colorimetric analysis at school. For the practical activity, we were asked to make up one of the solutions with part hydrochloric acid and part water. Since this was a colorimetric analysis, why was this done? Do I need to provide more information in this question or is what I have provided sufficient

I think we need to know more about your experiment to understand what you did... My feeling is that the acid was just used to acidify the substrate (i.e.: acting as a buffer) so that there is a colour change. |
