Mysterious Powders

Lab Report- Kiara Ahlstrom


The test my group chose to run include: iodine to test for starch because only one powder (green) has starch, vinegar to test for chemical reactions because only 2 powders reacted, physical properties to compare the mysterious powder to the other powders, and alcohol to test for chemical reactions.


For iodine the powder tested for starch so we know it has green in it. The vinegar fizzed for about 60 seconds(1 minute) which means there is red in the mixture. And for the physical properties there was sticky, transparent crystals just like purple.
