The Gravimetric Estimation of Nickel: The nickel is precipitated as nickel dimethyl glyoxime by adding alcoholic solution of dimethyl glyoxime C 4 H 6 (NOH) 2 and then adding a slight excess of aqueous ammonia solution When the pH is buffered in the range of 5 to 9, the formation of the red chelate occurs quantitatively in a solution
7 Analysis of an unknown mixture of calcium and magnesium Carefully transfer 1000 mL of your unknown solution (you will receive only 100 mL) into a 250-mL Erlenmeyer titration flask Add 3 mL of the ammonia buffer to bring the pH to about 10; check with the pH meter If needed, a few drops of 1-M NaOH can be added to bring the pH to 10 .
For 001 M titrant and assuming 50 mL burette, aliquot taken for titration should contain about 035-045 millimoles of nickel (20-26 mg) If preparation of such sample is difficult, we can use different EDTA concentration end point detection End point of nickel titration is easily detected with murexide
general remarks Magnesium can be easily determined by EDTA titration in the pH 10 against Eriochrome Black T If the solution initially contains also different metal ions, they should be removed or masked, as EDTA react easily with most cations (with the exception of alkali metals)
