We are going to do vinegar be cause we are going to see if it fizzes. Litmus paper because we want to know if it is a base or a acid. PR, if it is a acid we want to know how strong of a acid it is.iodine because we wated to know if it had starch.
We think it is red, green, and purple. How we got this is we wrote down all the test results including the pr, iodine, vinegar, and the litmus paper tests. After that we matched all the information up and we found that the ones that matched the best were red, green, and purple.
We did this test so we could see what color it would turn and how strong of a acid it is.
The Iodine Test
We chose the iodine test because we wanted to know if it had starch or not.
The Vinagar Test
We did the vinegar test to see if it would fizz or not it did fizz, it fizzed for 30 sec.
