Question

How do i name this compound: Cu(NO3)2 ?

Answer 1

copper & nitrate.
Now, you need to figure out the oxidation state. You can do this by setting up an easy algebra expression.

x + 2(-1) = 0
x = oxidation state
the 2(-1) is TWO nitrate ions which both carry a -1 charge. and the = 0 is because the whole compound itself is NEUTRAL (meaning it carries no charge). Now, if you solve for "x". That's your oxidation state. And hence, you have: Copper (___) nitrate
