Gel Formation with Sodium Alginate and Calcium Chloride
Description: A sample of 1-2% sodium alginate is dissolved in water and is then expressed via syringe into 1% (0.1M or higher) calcium chloride solution. The resulting mixture creates a crosslinked gel that may be physically separated from the aqueous phase.
