For my 1st year 2nd trimester, I’m taking up Chemistry Lecture and Laboratory. My laboratory class is every Friday from 8:00 am- 11:00 am. We already had a lot of experiments and since I have my camera in our Protein Analysis experiment, I took some photos of our results.
In this experiment, we were asked to put a solution of Copper II and Sulfate together with Sodium Hydroxide on a substance and when the color changes to purple, it means that the substance contains protein. When it changes to blue, it does not contain any protein.
Thanks a lot. I hope you learn something from this post.
