Reaction Classification Questions
1. Identify the reaction type: H2SO4(aq)+2LiOH(aq)→2H2O(l)+Li2SO4(aq)H_2SO_4(aq)
+ 2LiOH(aq) \rightarrow 2H_2O(l) + Li_2SO_4(aq)
A. Precipitation
B. Acid-Base
C. Gas Evolution
D. Oxidation-Reduction
Correct Answer: B. Acid-Base
Rationale: This is an acid-base reaction because sulfuric acid (H₂SO₄) reacts with lithium
hydroxide (LiOH) to form water and a salt.
2. Identify the reaction type: Mg(s)+Cu(NO3)2(aq)→Mg(NO3)2(aq)+Cu(s)Mg(s) +
Cu(NO_3)_2(aq) \rightarrow Mg(NO_3)_2(aq) + Cu(s)
A. Precipitation
B. Acid-Base
C. Gas Evolution
D. Oxidation-Reduction
Correct Answer: D. Oxidation-Reduction
Rationale: Magnesium (Mg) loses electrons (oxidation), while copper (Cu) gains electrons
(reduction), making this a redox reaction.
3. Identify the reaction type: HCl(aq)+(NH4)2S(aq)→H2S(g)+2NH4Cl(aq)HCl(aq) +
(NH_4)_2S(aq) \rightarrow H_2S(g) + 2NH_4Cl(aq)
A. Precipitation
B. Acid-Base
C. Gas Evolution
D. Oxidation-Reduction
Correct Answer: C. Gas Evolution
Rationale: This reaction produces hydrogen sulfide (H₂S) gas, characteristic of gas
evolution reactions.
4. Identify the reaction type: NaCl(aq)+AgNO3(aq)→AgCl(s)+NaNO3(aq)NaCl(aq) +
AgNO_3(aq) \rightarrow AgCl(s) + NaNO_3(aq)
A. Precipitation
B. Acid-Base
C. Gas Evolution
D. Oxidation-Reduction
Correct Answer: A. Precipitation
Rationale: The formation of an insoluble solid (AgCl) from two aqueous solutions confirms
a precipitation reaction.

A. Precipitation
B. Acid-Base
C. Gas Evolution
D. Oxidation-Reduction
Correct Answer: D. Oxidation-Reduction
Rationale: Magnesium (Mg) loses electrons (oxidation), while copper (Cu) gains electrons
(reduction), making this a redox reaction.

A. Precipitation
B. Acid-Base
C. Gas Evolution
D. Oxidation-Reduction
Correct Answer: A. Precipitation
