In the given statements the number of statements are incorrect Statem

1.	In the given statements the number of statements are incorrect Statement-1 : Hydrated Cu(II) salts are blue and anhydrated salts Cu(II) salts are colourless. Statement-2 : HgCl_(2) A white sublimable substance that in solution forms a white precipitate with NH_(3) Statement-3: Separation of Cu^(+2) and Zn^(+2) ions is not possible by using NaOH. Statement-4 : Pb^(+2), Ag^(+) cations can be separated by using an NH_(3) solution.
Answer» SOLUTION :In the given statements the NUMBER of statements are incorrect Statement-I : Hydrated Cu(II) SALTS are blue and anhydrated salts Cu(II) salts are colourless. Statement-2 : `HgCl_(2)` A white sublimable substance that in solution forms a white precipitate with `NH_(3)` Statement-3 : Separation of `Cu^(+2)` and `Zn^(+2)` ions is not possible by using NAOH. Statement-4 : `PB^(+2), Ag^(+)` cations can be separated by using an `NH_(3)` solution.
