AUTOlIhTIC TITRATIOX 01: CZl AND i\lf$ 569 2\ chrcct automatic dcrivatlb*c spcctrophotomctrlc EDTh tltratton procdure for tlctermination of calcium and magncslum in Dolomltcs and Limcstoncs ib tlcscribecl. Calcium is automatically titratctl In the prcscncc of magnesium at pH 13 using Calcon as indicator. and tllc total amount of calcium and magnesium at pH IO using Eriochrome Black T 'as lnclicator l'hc mcthotl is simple, precise ancl accurate. and rccluircs less than 5 min for both titrations.
