Here I'am again, and thanx Wayne for the info. Now I got this doubt,
is K2Cr2=7 soluble in water or in C6H6?
Wich is the reaction (ecuation) Fe(OH)3 + oxalic acid
" " " " " + Citric acid
" " " " AgCl + NH4OH +Zn ....

Are we having problems with homework? Are we too lazy to crack a
textbook?

Potassium dichromate is soluble in water as such, and in benzene with
crown or crypt ethers.

Iron(III) hydroxide forms the tris chelate with oxalic acid, and is
thereafter photosensitive. The citrate chelate forms analogously.

Tetraamminesilver(I) undergoes redox with zinc, which is also avidly
coordinated by ammonia.

If you submit these answers as such, you will get a failing grade for two
reasons:

1) They are incomplete.
2) You cannot justify the technical knowledge as your own.


TTFN.
