What is it, on a molecular level, that gives acids and bases their distinctive qualities. For example, what does the concentration of hydronium ions have to do with the sourness of acidic substances and what do hydroxide ions have to do with the soapy feel of bases?

Hydronium ions trigger taste buds that send a signal of "sourness" to the brain.

Hydroxide ions break down fatty acids and oils on the skin which reduces friction on your skin, which is why they feel soapy.
