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. Salts containing Cl -, Br -, or I - are generally soluble. If the amount of solute is exactly the same as the solubility it is saturated. Ask below and we'll reply! Sorry i interpreted the question wrong BaF2 is more soluble than BeF2 because for molecules having small anions like flouride , oxide ,hydroxides etc solubility increases down the group because lattice energy decreases .If you fund it useful please approve it.
