Natural Dyes Lab: Cogent Industry Example
Natural Dyes Lab: Cogent Industry Example
Students learn about an innovative greener alternative to the polyester manufacturing process as they investigate chemical bonds, fibers, pigments and dyes by extracting natural dyes and experimenting with pH and mordants.
Recycling Polylactic Acid
Recycling Polylactic Acid
Students extend the lifetime of a renewable product, a polylactic acid (PLA) plastic cup, by chemically converting the cup into a cleaning solution via a base hydrolysis.
NEW! Kit available from Flinn Scientific.
Supplement the PLA Lab with a titration extension.
Wood Ash Titration
Wood Ash Titration
Introduce acid-base titrations with a new spin. This green chemistry version of a strong acid-base titration uses wood ash, a renewable source of base, in place of NaOH.
