Does clay absorb water because of polarity?
One can indeed estimate whether a material is hydrophilic based on its chemistry: water likes to form hydrogen bonds and water complexes (e.g. around Na+). … In fact (as easily observed when burning earthware) clay gets more voluminous with higher water content. …

What is a hydrogen bond?
This also explains the general geometry of water (and ice).
As you know in water the hydrogen is covalently bonded to oxygen. … Now these positive H nuclei can bond to "full" electron clouds (e.g. the two of oxygen in water that are not bonded to hydrogen)
For something to be suluble in water you need to have many of those polar …
