- Pre-lab Answers . 1. What is sodium polyacrylate? Sodium polyacrylate is a water soluble polymer. The chemical structure of the polymer is shown below. The basic polymer is poly(acrylic acid), which has a carboxylic acid group on each repeat unit. In sodium polyacrylate, the carboxylic acid groups are neutralized with a sodium counter-ion. 2. What is the difference between hydrophilic and hydrophobic? Which part of a diaper is hydrophobic? Hydro mean water. Philic mean loving, so hydrophilic is water loving. Phobic means hating, so hydrophobic is water hating.

Sodium Alginate (alginate, algin) Sodium Alginate Origin. Sodium Alginate is a natural polysaccharide product extracted from the cell wall of brown seaweed that grows in cold water regions. The natural function of alginate is to give flexibility to the seaweed, so it is common to find higher contents of alginate in species found in troubled waters.n presence of calcium, sodium alginate forms a gel without the need of heat. In modernist cuisine, sodium alginate is mostly used with calcium salts to produce small caviar-like and large spheres with liquid inside that burst in the mouth.

Sodium bicarbonate Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is a chemical compound with the formula Na HCO3. Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder.It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate).aHCO 3 is mainly prepared by the Solvay process, which is the reaction of sodium chloride, ammonia, and carbon dioxide in water. Calcium carbonate is used as the source of CO 2 and the resultant calcium oxide is used to recover the ammonia from the ammonium chloride.
