Question 16

How do you determine the oxidation state of a cation that is not from group 1 or 2 (or al ag sc zn ga)

Answer 16

Number of e- in anion multiplied by how many of the anion are present

Divide by number of cations to get the number of e- which must be present in each cation

Ex- Ti(CN)3= titanium (III) cyanide

CN-1⃣ (3) = 3
Ti=1
3/1=3
