  • May 17, 2015 · The fluoride which is most soluble in water is: a)CaF 2 b)BaF 2 c)SrF 2 d)BeF 2 Homework Equations none The Attempt at a Solution the answer given is D. but BeF 2 is covalent in nature and is soluble in organic solvents. Due to more electropositivity of Ba, BaF 2 will have more ionic nature. On the other hand, since F is smaller compared to Ba, according to Fajan's rule, it can easily polarize Ba and it will have more covalent nature.
  • Well, let's think of why one compound is soluble in water while the other isn't. When an ionic compound is formed, energy is released. So, to dissolve in water, the ions have to 'overcome' the lattice energy. How? Of course, the net resulting attractions between water molecules and the ions...
  • A molecule is the smallest amount of a chemical substance that can exist. Such as the smallest amount of water one can have is a molecule of water or H20. It is made of up different atoms together; hence it can be separated back into the different atoms. Compounds are divided into two main categories: organic compounds and inorganic compounds.

  • Most ionic compounds are soluble in water because the electrostatic forces of the polar water molecules are stronger than the electrostatic forces keeping. Water is a covalent compound composed of one oxygen atom and two hydrogen atoms. While the bond is classified as covalent...
  • 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.
