Thinking about the salt in water experiment now, its clear that the salt- also known as NaCl or sodium chloride, would be highly soluble according to our solubility rules. Barium fluoride is an inorganic compound with the formula Ba F 2. Chromates are frequently insoluble. Generally, the solute is a solid and the solvent is a liquid, such as our salt in water example above. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration, where adding more solute does not increase the concentration of the solution and begins to precipitate the excess amount of solute. The answer that Barium fluoride is Slightly Soluble in water. A solution is considered saturated when adding additional solute does not increase the concentration of the solution.
