Chemical Properties of Water
The small size of hydrogen atoms makes it possible for molecules of water to effectively bond together or chemically associate, particularly at lower temperatures. This gives water its surface tension and liquid properties and also gives water it's unique physical properties [link here]. However, water also partially dissociates into very ...
