It depends on the reaction. The oxidation of an aldehyde gives a carboxylic acid, so RCHO -> RCOOH.
With potassium dichromate, there is water formed:
3CH3CHO + Cr2O72- + 8H+ -> 3CH3COOH + 4H2O + 2Cr3+.
Reacting an aldehyde with Benedict's solution uses water:
2Cu2+ + RCHO + OH- + H2O -> Cu2O + RCOOH + 3H+.

If you just use [O] in an equation as the oxidant, there will be no water. Using a real oxidant, there probably will be.
