CO2H I~H2 HCOH 02H, while the natural xylose, which produces l-tartaric See also:

acid by the substitution of CO2H for CHO.CHOH, corresponds to chloric, nitric, chloric, acetic, formic, sulphuric, oxalic, phosphoric, perchloric acids the specific rotation (calculated for the See also:base) only varies from -272° to -288°; H. H. Landolt found the same thing for active acids, the mono See also:lithium, See also:sodium, See also:potassium and ammonium tartrates varying only between 27.5° and 28.5° (calculated for the acid). A corresponding See also:rule may be expected where both base and acid have rotatory See also:power; the molecular rotation will be the sum of those for base and acid in salts with inactive radicles.
