Question

What is the role of NAOH in the thioacetamide reagent

Answer 1

Answer:

The ionization ratio of thioacetamide in aqueous sodium hydroxide, determined spectrophotometrically, is proportional to the concentration of hydroxide ion up to a concentration of about 1 M, and indicates a pKHA of 13.4. For more concentrated solutions the ionizing power increases more rapidly than the hydroxide ion concentration; from the experimentally determined ionization ratios the values of the h− acidity function for 1–6 M sodium hydroxide have been calculated. The relation of h− values to the salting-out parameters and water activities of concentrated sodium hydroxide solutions is discussed.
