Complexometric determination of calcium - Titration

general remarks. Calcium can be determined by EDTA titration in solution of 0.1 M sodium hydroxide (pH 12-13) against murexide. Just like during determination of magnesium all metals other than alkali metals can interfere and should be removed prior to titration. Magnesium in that high pH precipitates as Mg(OH) 2 and is not complexed by EDTA, thus its presence can be ignored.

Reaction with water | ToppersCBSE

Calcium and magnesium when react with water then some of hydrogen gas formed during the reaction get attached with their surfaces. Due to this calcium and magnesium start floating over the surface of water during reaction. Aluminium, iron and Zinc are less reactive metals so this coine only with water vapours to form metal oxide and hydrogen gas.

Chemical Reactions of CO2 in Water | SpringerLink

Abstract. The gas CO 2 is quite soluble in water in which more than 99% exists as the dissolved gas and less than 1% as carbonic acid H 2 CO 3, which partly dissociates to give H +, HCO 3 −, and CO 3 2 −.The subsequent contributions deal with the central role CO 2 plays in the living organism, whereas here we restrict ourselves to the reaction between CO 2 and water.
