Abstract

1. The polarographic behaviour of amino-acid complexes of zinc has been studied using seven amino acids as complexing agents. 2. The effect of varying the pH of the base solution and the concentration of amino-acid anion on the polarographic behaviour of zinc in these solutions have indi cated the formation of twelve amino-acid complexes. The stability constants could not be calculated due to the irreversible nature of the waves. 3. The effect of sodium hydroxide, sodium carbonate, and ammonia on the polarographic behaviour of zinc has been investigated. The results can be interpreted as due to the formation of mixed complexes in many systems. 4. Amino-acid base solutions have been found to be suitable for the polarographic estimation of zinc.
