Calcium and magnesium indicators in titration is discussed. Chromium black T (EBT) -emulsifier OP-picric acid system as the indicator of the calcium and magnesium contents and calcium indicator (NN) —emulsifier OP-picric acid system as the indicator of titration are determined. The terminal color change is acute. This method is used in the determination of the calcium and magnesium contents in samples such as dolomite, limestone and open-hearth furnace slag, with a relative windage of ±0.2%.
