Mysterious Powder
Lab Report
Tests-
Vinegar, iodine, PR, and PH we did iodine to see if it had starch. We did vinegar to see if it would fizz. We did PH to see if it had litmus paper. We did PR to see if it's and acid or a base.
Results/Conclusions-
We mixed all the powders together and all the liquids to see if it would fizz and it didn't but it did turn purple.
Learning Message-
I learned that if you cross contaminate it could ruin your whole test because it'll turn different colors instead of the ones it is suppose to be.
PR
We used PR to see if it's an acid or a base and after we mixed it, it turned to a gooey pink.
Vinegar
We used vinegar to see if it fizzes witch it did.
PH
We used PH to see if it was litmus paper witch it was it was #8.
Iodine
We used iodine to check for starch so when we added iodine it turned black and so it does have starch.
