- Eriochrome black T is the indicator used in complexometric titrations. In the presence of metal ions the indicator gives a wine red colour in the pH range of 7 to 11.At the end point, all the metal ions are converted into metal -EDTA complex & the free indicator is liberated which has blue colour.
“Chemistry Experiments” is a guide for students and teachers who look for various experiments in chemistry. I will be mainly focusing on chemical, fertilizers, water, effluent, latex, dry rubber testing in my latest blog. I hope these experiments will definitely help students & teachers. Please mail me if you all need any further assistance or help in any of these tests.
