Explain how the presence of several oxygen atoms ina compound containing an-oh group can make the compound acidic.

The factors to consider

Two of the factors which influence the ionisation of an acid are:

In these cases, you seem to be breaking the same oxygen-hydrogen bond each time, and so you might expect the strengths to be similar.

explanation:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
