About this document
EDTA Titration for Calcium Determination by Jela is a document available to read on EtoBox.
The document describes a procedure for determining calcium concentration using EDTA titration. EDTA solution was standardized against calcium carbonate and then used to titrate a water sample buffered to pH 10. The endpoint was identified by a color change from wine red to royal blue. Calculations are provided to determine the mass of calcium carbonate and total hardness based on the titration volume and sample volume. EDTA forms stable complexes with calcium and magnesium ions used for the analysis.
