Which reaction does not involve neutralization? A. H 2 SO 4 + 2NH 3 > (NH 4 ) 2 SO 4 B. H 2 SO 4 + BaCl 2 > BaSO 4 + 2HCl C. H 2 SO 4 + CuO > CuSO 4 + H 2 O D. H 2 SO 4 + 2NaOH > Na 2 SO 4 + 2H 2 O

B. H2SO4 + BaCl 2 > BaSO4 + 2HCl

Explanation:

Neutralization reactions are characterized by their reactants of acids and bases reacting to form salt and water. All of the options except B, have formation of salt and water. Also, B is more likely a percipitation reaction (also a double displacement reaction) and not neutralization.
