Question

what is the role of magnesium in complexometric titration

Answer 1

Answer:

Magnesium can be easily determined by EDTA titration in the pH 10 against Eriochrome Black T. If the solution initially contains also different metal ions, they should be removed or masked, as EDTA react easily with most cations (with the exception of alkali metals). Calcium can be precipitated as carbonate or oxalate, although presence of oxalates may make end point detection difficult.
