36.Number of moles of AgCl precipitated when excess of silver nitrate solution is added to A,B and C respectively A=CoCl3 .6NH3 (yellow) B=CoCl3 .5NH3 ( purple ) C=CoCl3.4NH3 ( violet )

Q. When $AgN{O}_3$ solution is added in excess to $1M$ solution of $Co{Cl}_3.xN{H}_3$ one mole of $AgCl$ is formed? What is the value of $x$?

Q. A sufficient amount of $AgN{O}_3$ solution was added to a solution containing $23.35g$ of the complex salt $CoC{l}_3\cdot 4N{H}_3$.

Q. A few drops of silver nitrate solution are added to a solution of a salt. If a pale yellow precipitate forms, which ion from the salt is most likely to be in the solution?

Q. A metal nitrate (X) gives a white precipitate with ammonia solution, but the precipitate get dissolved on adding ammonium salt. Lead dioxide and concentrated nitric acid on boiling with a dilute solution of metal nitrate (X) produces a violet-red (or purple) colour solution. Small amount of metal nitrate (X) gives an amethyst-red bead with borax in oxidising flame when cold. The cation of metal nitrate is :

Q. Only two-third of the chlorine contained in the solution of the complex salt $CoC{l}_3\cdot 5N{H}_3$ were precipitated from it by silver nitrate. No cobalt or free ammonia were detected in the solution of the salt.
