a) What is the equilibrium that influences the colour change of the Eriochrome Black T indicator? b) Consider how ETDA coordinates to metal ions and then consider this ligand below. Could this ligand be substituted for EDTA in a similar experiment? Why? Identify all possible donor atoms in the structure c) What is the function of the buffer solution for this experiment? Consider the form of EDTA (H4Y) compared to the form in the reaction equation below: The reaction of ETDA with metal cations, e.g. Mn+, may be written as: Mn+ + H2Y2– = MYn–4 + 2 H+
