Identify the reaction types in equations 1, 2, 4, and 5. Use redox, precipitation, acid-base, and gas-forming
Question:
Identify the reaction types in equations 1, 2, 4, and 5.
Use "redox", "precipitation", "acid-base", and "gas-forming" but use each only once.
Indicate why you made these choices (e.g., indicate gaseous products, precipitates, etc.)
Cu (s) + 4HNO 3 (aq) → Cu (NO 3 ) 2 (aq) + 2H 2 O (l) + 2NO 2 (g).....................(Eqn. 1)
Subsequently, the copper (II) nitrate will be converted into solid copper (II) hydroxide, Cu(OH) 2 (Equation 2), which in turns is converted by heating into solid copper (II) oxide, CuO (Equation 3).
Cu(NO 3 ) 2 (s) + 2NaOH (aq) → Cu (OH) 2 (aq) + 2NaNO 3 (ag) .....................(Eqn. 2)
Cu(OH) 2 (aq) + heat → CuO (s) + H 2 O (g) ................................................(Eqn. 3)
Next the copper ions will be brought back into solution by converting copper (II) oxide into copper (II) sulfate, CuSO 4 (Equation 4).
CuO (s) + H 2 SO 4 (aq) → CuSO 4 (aq) + H 2 O (l) .....................(Eqn. 4)
CuSO 4 (aq) + 2Al (s) → 3Cu (s) + Al 2 (SO 4 ) 3 (aq) .....................(Eqn. 5)
