Verification of aluminium with morin
methanol morin solution F T R 11-23/25 S (1/2)-7-16-24-45
optionally blacklight lamp
- One adds a spatula-tipful aluminium sulfate into the test tube and dissolves this with approx. 1 ml water.
- Immediately a green-yellow fluorescent color arises, which under blacklight is especially beautiful to observe.
The reaction solution can be discharged into the drainage.
Morin forms with aluminium(III) a fluorescent complex.
