Hi everybody,

Which of the following reactions will happen at room temperature:

1. 2NaNO3 (aq) + CuCl2 (aq) -> Cu(NO3)2 + 2NaCl

2. 2NaNO3 (aq) + CuSO4 (aq) -> Cu(NO3)2 + NaSO4

TY

Quick hints:
a) check if the product are possible, and the reactive too (they seem fishy to me, did you copy them right?)
b) check for the solubility of the product

You are right. I have edited it.

Sodium chloride and sulfate are both the least soluble compounds in those solutions, so after evaporating, much of the sodium will be removed.
