Exam question - Colour is often used in chemistry to identify substances. Compare and contrast the origin of a copper(II) complex with the colour of the copper (II) ion in a flame test. You do not need to state any specific colours.
Predict the likely shape of the complex ion a) [Ag(CN)2]-
Predict the likely shape of the complex ion b) [Fe(CN)6]3-
Predict the likely shape of the complex ion c) [NiCl4]2-
Predict the likely shape of the complex ion d) [CrCl2(H2O)4]+
