We did iodine to test for starch. It does have starch but not alot
we did it to test for acid. It did have acid
To test for the colors.It is an 8
To see if it bubbled. It bubbled a lot and stank
i think it is red green yellow and orange we think green because there both positive for starch we think red because there both have acid we think yellow and orange because there the closest number to the mysterious powder.
