|
Three activites are presented based around the natural plant pigment anthocyanin as an acid/base indicator. In Activity 1 students utilize plant pigment chormatography In Activity 2 students extract anthocyanins and use them to formulate a qualitative pH scale In Activity 3 students use a natural acid/base indicator during a titration. This activity utilizes pH probes and excel to generate a titration curve. The activities create an opportunity to link inorganic chemistry concepts with examples from the biological world. This may help with student interest. |
