Light Emission during the Neutralization Reaction in Presence of a Chemiluminescent Radical Indicator

Naturevolume 199pages595596 (1963) | Download Citation



RECENT publications by Stauff et al.1–3 of the results of experiments in which light emission during neutralization of sodium hydroxide with sulphuric acid was observed have prompted us to submit herewith the results of somewhat similar experiments of our own which were conducted some time ago.
