Excerpt from Laboratory Manual of Elementary Chemical Physiology and Urine Analysis Solid organic substances when intimately mixed with a large excess of fine granular black oxide of copper and heated to a high temperature in a hard glass tube are decomposed and completely oxidized at the expense of the oxygen of the copper oxide. Carbon present is con verted into carbon dioxide and hydrogen into water. If the combustion tube is furnished with a delivery tube which dips beneath the surface of clear lime water the characteristic reaction for carbonates is given. Organic liquids are characterized by being inflammable or by yielding inflammable vapors. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
