Abstract

TITRIMETRIC ANALYSIS OF CALCIUM CARBONATE IN DIFFERENT BRANDS OF TOOTHPASTE AVAILABLE IN MARKET

Ajmal H.*, Henna Jilsha, Hasoora Hasan P., Lalprasanth M. L.

ABSTRACT

Amount of calcium carbonate present in the toothpaste available in Kerala was determined by the titrimetric estimation. Here we adopt acid base and complexometric titration for the determination of calcium carbonate. In acid base titration 0.1N sodium hydroxide is used as titrant and indicator is phenolphthalein, and in complexometric titration sample was titrated against 0.05M EDTA using mordent black 2 as indicator where ammonium-ammonium chloride buffer is to maintain pH. Generally a toothpaste contain 20% of calcium carbonate as abrasive after the experiment we identified that amount of calcium carbonate in different toothpaste are different, some may contain more amount of calcium carbonate while other contain less amount than the standard value.

Keywords: Calcium carbonate, Tooth paste, Acid base titration, Complexometric titration.
