Mysterious Powder

Lab Report

this is our physical property's test

we used this test to figure out whether or not the mysterious powder had crystal like powder in it. (it proved positive) Plus we used the physical property test to see if it had a certain smell or texture.


I believe that we have a mixture of red, purple, and green. My first reason to believe that is when i saw small clear crystals (hopefully purple) in the physical property test. Second is when the iodine turned dark brown (hopefully the work of green) for if it didn't have starch in it the iodine would have turned a orange color. Last of all we believe that it has red because of the results we got when we did the PR test.
