How to balance it, step by step
- Count the atoms of each element on both sides, as written.
- Start with the biggest formula, Cu(NO₃)₂: put 1 in front of it.
- Cu: 1 on the right. Put 1 in front of Cu.
- N: 2 on the right. Put 2 in front of AgNO₃.
- Ag: 2 on the left. Put 2 in front of Ag.
- Check: Cu 1 = 1, Ag 2 = 2, N 2 = 2, O 6 = 6. Balanced.
What happens
It is a displacement reaction: a more reactive element pushes a less reactive one out of its compound. A copper wire in silver nitrate solution gets coated with silver, and the solution turns blue.
Copper and silver nitrate: quick answers
What is the balanced equation for copper and silver nitrate?
Cu(s) + 2 AgNO₃(aq) → Cu(NO₃)₂(aq) + 2 Ag(s). The coefficients are 1, 2, 1 and 2. Each side then has 1 Cu, 2 Ag, 2 N and 6 O.

How do you balance Cu + AgNO₃ → Cu(NO₃)₂ + Ag?
Start with the biggest formula, Cu(NO₃)₂: put 1 in front of it. Cu: 1 on the right. Put 1 in front of Cu. N: 2 on the right. Put 2 in front of AgNO₃. Ag: 2 on the left. Put 2 in front of Ag. Never change a subscript, because that would change the substance.
