Students sometimes use HNO3 (aq) instead of H2SO4 (aq) in reaction E, Step 4, assuming that both strong acids will accomplish the same purpose. Briefly describe the consequences of this error. Reaction E: magnesium metal acts as a reducing agent to convert the aqueous copper (II) sulfate to pure (reduced) copper metal, Cu: CuSO4 (aq) + Mg(s) = Cu(s) + MgSO4 (aq) In a competing reaction, magnesium also reduces sulfuric acid, with formation of hydrogen gas and aqueous magnesium sulfate:...
Balance the equation for the reaction observed: _ Cu(s) + HNO3(aq) → Cu(NO3)2(aq) +_ NO2(g) + H2O(1) 3. Add 40 mL of 3.0 M NaOH (sodium hydroxide) to the solution in your beaker. Write the balanced equation for the reaction observed: 4. Add 2-3 boiling chips to your beaker and carefully heat the solution, while stirring with a stirring rod, just to the boiling point. (Do NOT boil. Have a low flame and keep the beaker well above the flame.)...
