Complexometric determination of nickel Titration

Nickel is titrated with EDTA against murexide. At the beginning of the titration solution should have low ammonia concentration, increased near the end point. This procedure enhances color change at the end point. Reaction between EDTA and Ni 2+ ions is relatively slow, so titration should be carried out slightly slower than in other direct EDTA...
