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 alkalinity.Sodium carbonate, also known as washing soda or soda ash, is a whi...
A previously published IR reflectance spectrum of Na 2S, a candidate surface component on Jupiter's satellite Io, showed a weak but distinct band at approximately 4.04 μm that was interpreted as due to chemisorbed H 2S or SO 2. New spectra have been obtained on Na 2S powder showing that ...
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...
