DOCUMENT TYPE: Journal CA Section: 58 (Cement, Concrete, and Related Building Materials) A complexometric method for the detn. of Ca and Mg in limestone using antipyrylazo III [14918-39-9] and thymolphthalexon [1913-93-5] is described. Potential interfering elements are masked with triethanolomine. In one aliquot, Ca is titrated at pH 13.0 with antipyrylazo III as indicator and in another aliquot Ca and Mg are titrated in NH3 buffer with thymolphthalexon indicator. .
