Question

Which reaction does not involve neutralisation? 1. H2SO4(aq) + 2NH3(aq) → (NH4)2SO4(aq) 2. H2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2HCl(aq) 3. H2SO4(aq) + CuO(s) → CuSO4(aq) + H2O(l) 4. H2SO4(aq) + 2NaOH(aq) → Na2SO4(aq) + 2H2O(l)

Answer 1

Answer:

4) option

Explanation:

mark me as branlist plssss

Answer 2

Answer:

2)

Explanation:

In option 2) Barium Chloride and HCL is being produced which isn't an neutralization reaction as no salt + water is formed/ Barium Chloride has a neutral pH values which means it isn't a base and reacting it with acid wont get us to a neutralization reaction. In option 3), 4) salt and H²O is being produced thus both are neutralization reactions. The 1) option is an acid-base reaction (neutralization): NH3 is a base, H2SO4 is an acid.
