title: A convenient method for determining the concentration of hydrogen in water: use of methylene blue with colloidal platinum.
abstract: A simple titration (oxidimetry) method using a methylene blue-platinum colloid reagent is effective in determining the concentration of hydrogen gas in an aqueous solution. The method performs as effectively as the more complex and expensive electrochemical method.
