I mixed the solutions of feso4 h2so4 and cu(no3)2 and received the solution of green and purple colors with no2 gas and white sediment. What could it be?
Accepted Answer
The reaction between FeSO4, H2SO4, and Cu(NO3)2 can result in the formation of green [Fe(H2O)6]2+ ions, purple [Cu(H2O)6]2+ ions, brown NO2 gas, and white CuSO4 precipitate. The overall reaction can be represented as:
2FeSO4 + H2SO4 + 2Cu(NO3)2 → 2[Fe(H2O)6]2+ + 2[Cu(H2O)6]2+ + 2NO2 + CuSO4
