Verified step by step guidance1
Identify the oxidation state of copper in Copper (I) nitrate. The Roman numeral I indicates that copper has a +1 oxidation state.
Determine the formula for the nitrate ion. Nitrate is a polyatomic ion with the formula NO3-.
Balance the charges between the copper ion and the nitrate ion. Since copper has a +1 charge and nitrate has a -1 charge, they combine in a 1:1 ratio to form a neutral compound.
Write the molecular formula by combining one copper ion (Cu+) with one nitrate ion (NO3-).
The molecular formula for Copper (I) nitrate is CuNO3.
