WebSodium carbonate has a melting point of 851°C, it decomposes when heated and therefore a boiling point can not be determined. Sodium carbonate is an inorganic salt and therefore the vapour pressure can be considered negligible. Its water solubility is 215 g/l at 20°C. WebMelting temperatures, Tm, were systematically studied for a set of 92 DNA duplex oligomers in a variety of sodium ion concentrations ranging from 69 mM to 1.02 M. The relationship between Tm and ln [Na+] was nonlinear over this range of sodium ion concentrations, and the observed melting temperatures were poorly predicted by … WebFor saltwater, the boiling point is raised, and the melting point is lowered. By how much depends on how much salt there is. I’ll assume the salt is sodium chloride, NaCl (table salt).
