Ni Dmg 2 Molecular Weight
Ni Dmg 2 Molecular Weight Calculator
We did a gravimetric analysis lab and I have masses for the DMG-Ni complexes that we recovered but I need to find the percent nickel in each sample.Relevant Equations: I believe you take the mass of the DMG-Ni complex sample and multiply that by the mass ratio of Ni2+ over the FW of DMG. Then divide the result by the mass of the sample and multiply by 100%.
Molar Mass, Molecular Weight and Elemental Composition Calculator モル質量と元素組成を計算するために化学式を入力してください: モル質量 of Ni(dmg)2 is 288.9146 g/mol. 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.

Ni Dmg 2 Complex
The Attempt at a Solution
I did what I layed out above but I get the same percentage Ni2+ for each sample which doesn't make sense so I must have gone wrong. Any help would be great![/B]
