Calcium is determined at pH 12 where magnesium is quantitatively precipitated as the hydroxide and will not react with EDTA.

Oxidation-Reduction Reactions: Redox - …

Redox reactions, or oxidation-reduction reactions, have a nuer of similarities to acid-base reactions. Fundamentally, redox reactions are a family of reactions that are concerned with the transfer of electrons between species. Like acid-base reactions, redox reactions are a matched set -- you don''t have an oxidation reaction without a

Redox Reactions | Protocol

Redox Reactions. Not all chemical reactions are classified as a redox reaction. A redox reaction is any reaction in which there is a change in an atom''s oxidation state. Thus, to check whether a reaction is a redox reaction, determine the oxidation states of each atom in the reactants and products and look for any changes.
