Methyl red and bromine reaction
WebBromine is a very reactive element. Indicators such as Methyl orange actually change colour due to a mechanism called tautomerism. This is when the molecule changes from one arrangement of atoms to another. One form is coloured A the other form B is a different colour. It usually involves the movement of hydrogen ions in the molecule, hence is pH … Web2. When all the phenol has reacted, the bromine continuously produced in the first reaction will then react with the methyl red indicator, bleaching its colour. 3. …
