Results and Conclusion

Results/Conclusion- So when we took the 4 test we found out many interesting things. We found out that the pH is 8 which is the same as red, green and purple. The powder also was grainy and fluffy so we assumed it came from the bakery.We thought about this decision very carefully and we decided it came bakery because to use it looked like flour, sugar and salt.For the iodine test it was 75% positive and 25% negative. For the alcohol test it made a slimy thick paste.
