Soda Ash, Na2CO3, is a sodium salt of carbonic acid. The pure product appears as a while, odorless powder with a strong alkaline taste. It has high hygroscopicity. It can be easily dissolved in water to form an aqueous solution with moderate alkal...
Because Raman scattering intensity of dispersed solute molecules is inherently weaker than that of crystals composed of the same compound, a high concentration of Na2CO3was necessary to generate sufficiently strong Raman signals. We therefore set the concentration of Na2CO3at 2 M, which was recommend...
