Sodium alginate is slightly soluble in water and insoluble in most organic solvents. It dissolves in alkaline solution and makes the solution viscous. Sodium alginate powder becomes wet with water, and the hydration of particles makes its surface viscous. The particles then quickly bond together to form a mass, which slowly fully hydrates and dissolves. If the water contains other compounds competing with alginate for hydration, sodium alginate is more difficult to dissolve in the water.

Calcium alginate can rapidly exchange ions and form gels. Using this property, alginate solution can be dripped into aqueous solution containing calcium ions to produce calcium alginate colloid.

Adding calcium ions into the alginate solution can produce gel jelly. The gel formed by calcium alginate and sodium alginate has thermal irreversibility.
