Chemistry and the Aquarium: Calcium
When calcium and carbonate ions are dissolved in water, a nuer of water molecules become tightly attached to the ions. This hydration is discussed in detail in the following section. Overall, however, the volume occupied by undissolved calcium carbonate and water is larger than the volume occupied by calcium and carbonate ions dissolved in this same amount of water.
Select Driers for High Solids and Waterborne Coatings
This is explained by the high solubility of oxygen in water, which saturates the paint layer with sufficient oxygen for the autoxidation process. Best drying and film appearance properties can be reached using water-emulsifiable metal-complexes in which cobalt is main drier: 0,08% Co and 0,1% Ca on binder solids is considered a good starting point for sicivation of waterborne paints .
