Question
For each of the molecular equations given below, identify the reaction as either an acid-base reaction, or a reduction-oxidation reaction, and write the total ionic and net ionic equations. For each acid-base reaction, identify the Bronsted acid and the Bronsted base reduction-oxidation reaction, identify the oxidizing agent and the reducing agent. H_2SO_4(aq) + Ca(OH)_2(aq) right arrow 2H_2O(l) + CaSO_4(S) 2NaBr(aq) + Cl_2(g) implies 2NaCI(aq) + Br_2(l) 2HNO_3(aq) + 6HCl(aq) + 3Fe(.s) right arrow 3FeCI_2(aq) + 2NO(g) + 4H_2O(l)Explanation / Answer
a) acid-base reaction:
H2SO4 + Ca(OH)2 = 2H2O + CaSO4
Bronsted acid: H2SO4
Bronsted base : Ca(OH)2
b) oxidation-reduction reaction.
2NaCl + Br2 = 2NaBr + Cl2
Cl is getting oxidised ( 2Cl- to Cl2), hence its the reducing agent
Br is getting reduced ( Br2 to 2Br- ), hence its the oxidising agent
c) oxidation reduction reaction:
oxidation : 3 Fe + 6Cl - = 3FeCl2 + 6e-
reduction: 2HNO3 + 6H+ + 6e- = 2NO + 4H2O
