Map Classify each of these reactions. O acid-base neutralization O precipitation O redox O none of the above O acid-base neutralization O precipitation O redox O none of the above Caols) + cole) CaCO,(s) O acid-base neutralization O precipitation O redox O none of the above KOH(aq) + AgNO,(aq) KNO3(aq)+Ag()H(s) O acid-base neutralization O precipitation O redox O none of the above Ba(OH)2(aq) + 2HNO,(aq) O acid-base neutralization O precipitation O redox O none of the above Ba(NO2)2(aq) + 2H20(2)Explanation / Answer
Ba(ClO3)2 (s) ----> BaCl2 (s) + 3O2 (g)
Answer : redox reaction.
Cl5+ is reduced into Cl- and O2- is oxidized into O.
2 NaCl (aq) + K2S (aq) ----> Na2S (aq) + 2 KCl (aq)
Answer : none of the above
( It is just cation / anion exchange reaction), There is no reduction/oxidation, No precipitaion, and there is no acid / base in this reaction.
CaO (s) + CO2 (g) ----> CaCO3 (s)
Answer : Acid-Base neutralization reaction.
Lux-Flood: an acid is an O2- acceptor, and a base is an O2- donor
CaO is oxide ion donor - Base
CO2 is oxide ion acceptor - Acid
KOH (aq) + AgNO3 (aq) ----> KNO3 (aq) + AgOH (s)
Answer : Precipitation reaction
one of the product is precipitate and there is no solid reactant .
Ba(OH)2 (aq) + 2 HNO2 (aq) ---> Ba(NO2)2 (aq) + 2 H2O(l)
Answer : Acid - base neutralization
Ba(OH)2 is Base
HNO2 is acid
