FREE Expert Solution

We have to determine, in which of the given reactions, the oxidation number of oxygen increases.


Oxidation is a reaction where the oxidation state of an element increases. So basically, we are determining the reaction where oxygen is being oxidized.


To determine in which of the reactions the oxidation state of oxygen increases, we have to determine the oxidation number of oxygen in each of the reactions.

In which reaction does the oxidation number of oxygen increase?

a. Ba(NO3)2(aq) + K2SO4(aq) → BaSO4(s) + 2KNO3(aq)

b. HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

c. MgO(s) + H2O(l) → Mg(OH)2(s)

d. 2SO2(g) + O2(g) →2SO3(g)

e. 2H2O(l) → 2H2(g) + O2(g)
