Appearance/Colour :colorless or light yellow fibrous powder
Solubility:Potassium alginate is soluble in water, dissolving to
form a viscous hydrophilic colloidal solution. It is insoluble in
ethanol (95%) and in hydroalcoholic solutions in which the
alcohol content is greater than 30% by weight; also insoluble in
chloroform, ether, and acids having a pH lower than about 3.
When preparing solutions of potassium alginate it is important
to ensure proper dispersion of the particles, as poor dispersion
will lead to the formation of large lumps of unhydrated powder
and significantly extended hydration times.
