What is named first the cation or anion? correct answer: Cation How many Ligands are in [Cr(NH3)6](NO3)3 correct answer: 6 How many Ligands are in K[Au(OH)4] correct answer: 4 Oxidation number of the metal in K[Au(OH)4]? correct answer: +3 explanation: hydroxide has a charge of -1, since there are a total of 4 hydroxides the total (-) charge is -4. The charge of K is +1. Therefore the charge of Au must be +3. +4 + (-4)=0 Within a complex ion ligands are named in _____________ ord...
