"Reducing agent" Quotes from Famous Books
... is an easy matter to obtain sodium nitrite (NaNO{2}), as the reaction given on the previous page indicates. Instead of merely heating the nitrate, it is better to heat it together with a mild reducing agent, such as lead, when the reaction takes place which is expressed ... — An Elementary Study of Chemistry • William McPherson
... slowly. The gold is left in a colloidal state. Copper when added to a glass produces two colors, blue-green and red. The blue-green color, which varies in different kinds of glasses, results when the copper is fully oxidized, and the red by preventing oxidation by the presence of a reducing agent. This red may be developed by reheating as in the case of making gold ruby glass. Selenium produces orange and red ... — Artificial Light - Its Influence upon Civilization • M. Luckiesh
... The deposition of gold being thus controlled, its loss by dispersion or from the crumbling away of the sustaining pyrites is nearly or quite prevented, a conservative effect which we could scarcely expect to obtain if organic matter were the reducing agent. Meanwhile there is a gradual wasting away of the pyrites or positive pole, its sulphur being oxidised to sulphuric acid and its iron to sesquioxide of iron, or hematite, a substance very generally associated with gold nuggets. According to the original size of the pyritous mass, ... — Getting Gold • J. C. F. Johnson
... mixture, the cavities formed by the explosion in the lead cubes used for test were found simply lined with soot; but up to the limit necessary for converting all the carbon in the dynamite into carbonic oxide, the addition of a reducing agent was shown to be an important gain.

... able to destroy a naval harbor, so long as water and stone were in conjunction. There was also a possibility that a small quantity of ozak, as the stuff was called, mixed with pure water, would form a reducing agent for limestone, and perhaps for other minerals, which would work much quicker than if the liquid was merely impregnated with carbonic acid gas. He endeavored to purchase some ozak from Mr. Kruger, the chemist on the English quay, but that good man had never heard of it, and ... — A Rock in the Baltic • Robert Barr |
