Question

Complete and balance the three equations according to acid and base behavior in water. Phase labels are optional. HNO3(aq)+H2O(l)⟶ Ba(OH)2(s)−→−−H2O HF(aq)+H2O(l)↽−−⇀

Answer 1

a) HNO3 (aq) + H2O (l) ↔ H3O+ (aq) + NO3- (aq)

b) Ba(OH)2 (s) + H2O (l) ↔ Ba2+ (aq) + 2OH- (aq)

c) HF(aq) + H2O(l) ↔ H3O+ (aq) + F- (aq)

Step-by-step explanation:

Answer 2

a) HNO3 (aq) + H2O (l) ↔ H3O+ (aq) + NO3- (aq)

b) Ba(OH)2 (s) + H2O (l) ↔ Ba2+ (aq) + 2OH- (aq)

c) HF(aq) + H2O(l) ↔ H3O+ (aq) + F- (aq)

Step-by-step explanation:

a) HNO3 (aq) + H2O (l) ↔ H3O+ (aq) + NO3- (aq)

nitrogen oxidizes, loses 1 electron and oxygen decreases, gains 1 electron

b) Ba(OH)2 (s) + H2O (l) ↔ Ba2+ (aq) + 2OH- (aq)

c) HF(aq) + H2O(l) ↔ H3O+ (aq) + F- (aq)
