Vinegar, ph , PR, Iodine
Our group chose to test with iodine, vinegar, ph, and PR.We chose iodine to test for starch.We chose to test with vinegar to see if would fizz. We chose to test the ph to see if it was an acid or bass. We also chose to test with PR to see if the powder was an acid.
My group thinks the mysterious powder is made up of green, red, and orange. We thought it was green because it test positive for starch. We thought it was red because it fizzed with vinegar. We also thought it was orange because it fizzed for 30 seconds with vinegar.
