Description:

Schematic drawing of the chemical reaction between sodium alginate and calcium chloride. On the left side sodium alginate molecules are depicted. Lines represent the alginate molecules and green circles represent the sodium ions that are associated with the alginate. On the right side the calcium alginate is shown. Again lines represent the alginate molecules and orange circles in between the lines represent the calcium ions. Each calcium ion binds two strands of alginate.
