The acidic composition can be prepared by mixing a monovalent or polyvalent cation and an organic acid in the presence of a strong oxyacid, wherein the resultant acidic composition is less corrosive to a ferrous metal than a solution of a mineral acid having the same acidic pH value as that of the acidic composition, and where in the acid composition is more biocidal than a mixture of the organic acid and a metal salt of the organic acid which mixture has the same acid normality value as that of the acidic composition.

所述酸性组合物可以在一种强羟基酸存在时，通过混合单价或多价阳离子和有机酸来制备，其中与具有相同的酸性pH值的无机酸溶液相比，所形成的酸性组合物对含铁金属的腐蚀性更小，并且与具有相同酸当量值的有机酸与有机酸金属盐的混合物相比，所述的酸组合物具有更强的杀生物作用。
