ABSTRACT:
Chromazurol S reagent from violet complex with chromium (III) in wave length (550 nm). The complex was found to be stable for at least 2 hour the given pH. Beers, law is obeyed in the concentration range (1.923×10-5- 2.693×10-5 M) with molar absorptivity of (1.233×104 L.mol-1. Cm-1). The stoichiometry of complex was confirmed by using mole ratio and molar method which indicated the ratio of reagent to metal is (3:1). Measuring conductivity at room temperature the ionic character of the complex. Has been appointed the melting point of the complex and found that the degree of melting is (231-233C). The study of several factors, including the interactions resulting from the presence of positive or negative ions effect, masking agents, reagent concentration, reaction time sequence of additions.
KEYWORDS:
Chromazurol S reagent, stoichiometry.
