In synthesizing Nickel salt complex, why is ethanol used?
Homework Answers
Ethanol is used for crystallize the nickel salt form the solution. But most of the time it is not enough to crystallize. So Ice & ethanol along with dry ice are used .

A solid sample of a complex salt, with ideal composition
Ni(NH3)6(NO3)2, was
analyzed for nickel by dissolution in slightly acidic solution and
precipitation as the dimethylglyoximate, Ni(DMG)2.
A sintered glass crucible of mass 13.2379 g was used to filter
off the precipitate. The dried crucible and precipitate had a
combined mass of 13.3319 g.
Calculate the theoretical mass of the original
Ni(NH3)6(NO3)2
sample.
0.0927 g
You are correct.
Your receipt no. is 152-9832
