Simple yet Fun Friday

Hello Everyone!

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.

Our results.

Water.

Green Peas

Soy Milk

Egg

Glucose

Milk

Glycogen

Yogurt

Cheese

Thanks a lot. I hope you learn something from this post.
