Answer to Question #187459 in Inorganic Chemistry for Naorem KamalKishore Singh

Question

Calculate the amount of Ni2+ ions in given solution where

Mass of empty sintered glass crucible = 15.6379 g

Mass of empty sintered glass crucible + Ni-DMG after first heating = 15.6528 g Mass of crucible after second heating = 15.6520 g

Mass of crucible after third heating = 15.6520 g

Answer 1

Mass of sintered glass crucible = a g.

 

Mass of sintered glass crucible + nickel complex = b g.

 

Mass of dimethyl glyoxime nickel complex = (b-a) g.

 

288.69 of nickel complex contain 58.69 g of nickel.

 

Mass of nickel in (b-a) g of complex .

 

Therefore, Mass of nickel in the whole of the given solution .
