What are some possible scientific investigations that can be done with dyes and textiles?
On a high school level, say the acidity of dyes on textiles and the textile’s combustion point. Please provide details, thanks!
Additional Details
I need two independent variables to investigate, thanks!
Do not do combustion. You do not have the required equipment in a high school lab and it can be dangerous. Do the pH, do color, do conductivity, do color treatability by adding (not at the same time) acids or hydrogen peroxide or ferric chloride at pH 9. 5 to determine color stability. You can also look at the types of additives present by testing for sugars, carbonate, and sulfate.
If you take dyed fabric, test the stability of the color to chlorine bleach, oxyclean, acids, etc.
