Unit 2 PPA 1 Complexometric Determination of Nickel using EDTA Introduction: The Aim of the experiment is to determine the percentage of nickel salt using a complexometric technique. Ethylenediaminetetraacetic acid (EDTA) is a hexadentate ligand which forms stable complexes with most metal ions‚ thus is widely used to determine metals in complexometric titrations. EDTA can be represented as H4Y and in alkaline conditions‚ it exists as Y+ ions: The Y4- ions form 1:1 complexes with metal ions

What is the effect of a non-volatile impurity on the boiling point of a substance? of a volatile impurity? A non volatile impurity which is added to the volatile liquid‚ it’s boiling point will increase. It is due to some of effective surface area which is available for evoperation is occupied by non volatile substance. If another volatile impurity is added then 1) if it does not chemically react with given liquid then boiling point will decreade due to increase in vapour pressure. 2) if it chemically
