For are four test we did iodine, oil, PR, and vinegar. Iodine test for starch. Oil to see if it separates. PR is to test to see if it is a aside. vinegar is to see if it will fizz or have a chemical reaction.
PR test tuned bright pink
iodine test tunes black and looks like oil
the vinarger test had a cemical reaction and fizzed
the oil looked clear and separated
we think its red because it tests for PR we also thought it was green because of the iodine test.
