A method for quantifying magnesium ions in a solution or sample (e.g., a latex sample). The method includes adding a composition or solution that includes sulfide ions for selectively precipitating interfering metal ions (i.e., non-magnesium ions). The sulfide ions are added to the latex sample in a controlled manner. In addition, the method includes using a complexometric titration process with EDTA as a titrant to determine the quantity of magnesium ions present in the sample (e.g., latex sample). The selective precipitation, and removal, of interfering metal ions facilitates or effectuates a more accurate quantification of magnesium ions in the sample (e.g., latex sample).
