Hey buddy,
● Answer - [CrCl(H₂O)₅]Cl₂.H₂O
● Explaination-
When CrCl3.6H2O complex is treated with AgNO3, it gives a white precipitate of silver chloride.
[CrCl(H2O)5]Cl2.H2O + 2AgNO3 ---> [CrCl(H2O)5](NO3)2.H2O + 2AgCl
Thus, formula of the complex is [CrCl(H₂O)₅]Cl₂.H₂O and IUPAC name is Penta-aqua-chlorido-chromium(III)Chloride .
