Calculate the solubility in grams per liter. In its elemental form, barium is a soft, silvery-gray metal. Barium Chromate NONE. These are handy rules for us to have if we deal with salts often. Barium (atomic symbol: Ba, atomic number: 56) is a Block S, Group 2, Period 6 element with an atomic weight of 137.27. A compound's molar solubility in water can be calculated from its K value at 25C. 0000027985 00000 n 0000086541 00000 n Solubility The maximum amount of a solute that will dissolve in a given amount of solvent at a given temperature is called is called the solubility of that solute in that solvent at that temperature.
