HOW MUCH DYE IS THERE IN A COUGH SWEET?

Audience: Year 12 students

Duration: 2-2.5 hours

Location: This experiment will be carried out in our laboratory.

 

The aim of the experiment is to work out how much dye is needed to give its colour to a cough sweet. Students will use UV-Vis spectroscopy and will practice their analytical skills, making various dyes solutions at different concentrations.
