Given KNO3 + CuSO4 is a double replacement reaction, predict the products and then determine whether you would expect to see a precipitate or not.​

Answer:

Products will be K2SO4 and Cu(NO3)2. A precipitate will not form.

Explanation:

Double replacement reactions are the switching of cations between two compounds. So in this case, the K+ and Cu 2+ cations will switch places.

KNO3 + CuSO4 -> K2SO4 + Cu(NO3)2

According to solubility rules, any substances containing NO3 or a Group 1 ion (K+ in this case) will be definitely soluble. There are a few exceptions to the Group 1 rule but it does not apply here. Potassium sulfate (K2SO4) contains a Group 1 ion so it will be soluble and not be a precipitate. And copper nitrate (Cu(NO3)2) contains nitrate so it will also be soluble and not be a precipitate.
