Webmade a number of determinations of the molecular conductivity of nitric acid, diluted so as to contain a gram-molecular weight in volumes of water varying from 2 to 8,192 litres. ... sulphuric acid.; the pale yellow acid thus obtained was then redistilled with barium * ' Zeits. Physikal Chem.,' vol. 14, p. 317, Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade is more stable in storage, and is the usual form of what is described as "concentrated sulfuric acid". Other concentrations are used for different purposes. Some common concentrations are: "Chamber acid" and "tower acid" were the two concentrations of sulfuric acid produced by the le…
