We have studied the oxidation of benzyl alcohols by nitrous and nitric acid in sulfuric acid media. The oxidation by nitrous acid is rapid and has an activation energy of 10.6 -t 0.8 kcal mol-'. A Hammett plot of logkp vs. u -is linear with a p value of -1.4. The oxidation by nitric acid in sulfuric
The morphology and surface roughness of silver (Ag) deposit formed on metallic copper (Cu) by cementation conducted in a 0.5M H 2 SO 4 solution was investigated at various temperatures above 258. The influence of the presence or absence of oxygen (O 2 ) on Ag morphology was studied at an initial Ag
