It is a chemistry lab project where we took silver nitrate mixed it in water and put a coiled copper wire in to the solution. I need to know why the solutions color changed when the reaction started. The color the solution turn to was blue. If you can answer this it would mean alot to me its a lab question due tomorrow thank you.

Silver is reduced from Ag+ to Ag, while copper is oxidized from Cu to Cu2+. Cu2+ ions are blue in solution (has to do with the electron configuration of Cu2+, which is 3d9, and electrons being excited by light into higher orbitals and emitting light in the appropriate wavelength for blue light).

well 2AgNo3 + Cu ---> 2Ag + Cu(NO3)2
well is it because CuNo3 is blue? also, Nitrate makes stuff pretty soluble, right?
