Green
Violet
Purple
Blue
Which of these are the correct colours for the metal aqua ions listed?
Cu (II) - Blue Solution
Fe (III) - Green Solution
Cr (III) - Purple Solution
Ni (II) - Blue Solution
Mn (II) - Pale Pink Solution
Zn (II) - White Solution
Fe (II) - Green Solution
Which of the following transition metals display a change upon the further addition of hydroxide ions (assuming small amounts have already been added)?
Cu (II)
Cr (III)
Ni (II)
Zn (II)
Fe (II)
Copper (II) forms a deep blue solution upon addition of excess hydroxide ions.
Which of these is the correct change observed for the transition metal ion listed upon the addition of small amounts of hydroxide ions or ammonia?
Cu (II) - Blue ppt forms
Fe (III) - Green ppt forms
Fe (II) - Brown ppt forms
Mn (II) - Pink ppt forms
Zn (II) - White ppt redissolves to form colourless solution
Cr (III) - Green ppt forms
Ni (II) - Green ppt forms
Chromium is the only transition metal to display amphoteric behaviour?
Zn (II) will have how many ammonia groups bonded to it as a complex ion?
2
4
6
3
+6 is the most stable ion of Chromium.
Copper is the only transition metal for form +1 ions.
Cu (I) is unstable and will undergo disproportionation in solution.
Cu (I) compounds aren't coloured due to it having a full 3d subshell.
Cisplatin is what shape?
Tetrahedral
Linear
Square Planar
Octahedral
Trigonal Planar
