Question

Write the principle of estimation of Calcium and Magnesium ions in water?​

Answer 1

Answer:

The determination of the Calcium and Magnesium next together in water is done by titration with the sodium salt of ethylenediaminetetraethanoic acid (EDTA) at pH 8 - 9, the detection is carried out with a Ca electrode. The result is calculated as mg/l Ca2+ respectively mg/l Mg2+.

Answer 2

Answer:

The determination of the Calcium and Magnesium next together in water is done by titration with the sodium salt of ethylenediaminetetraethanoic acid (EDTA) at pH 8 - 9, the detection is carried out with a Ca electrode. The result is calculated as mg/l Ca2+ respectively mg/l Mg2+.Instead of repeatedly drawing this structure or writing out the chemical formula, the EDTA molecule is represented as “H4Y”.
