Simple Analysis of Gluconate in Cleaner

Associate Chemist, NYC Transit Authority Chemical Laboratory, Brooklyn, NY

Abstract

Two simple methods of gluconate analysis in a cleaner are described:

1. Gluconate is oxidized by periodate. The amount of formic acids are titrated by standard alkaline. 2. In the presence of acidic iodide solution, gluconate oxidized by hydroperiodic acid liberates iodine. At the same time its unreacted acid also liberates iodine. The amount of iodine is titrated by standard sodium thiosulphate.
