Organic acids can thus substantially affect the amounts and ratios of elements going into solution from minerals. 因此有机酸对各种元素从矿物进入溶液的数量和比率都起着重大的影响。 These compounds make up approximately 10 to 15% of the total organic matter in soils. 这些化合物占整个土壤有机质总...

Unsaturated acids exhibit chemical properties expected of compounds that contain both a COOH group and one or more carbon-carbon double bonds. Like all carboxylic acids, they are acidic; can be reduced to alcohols; can be converted to acid derivatives; and, like other compounds containing double ...
