Document Summary
When we write molecule like this, nacl (aq), we really mean that na and cl ions are surrounded by. We get energy back from solvating ions, known as solvation enthalpy, and in. Chemical bonding unit its explained that energy is released when gas-phase ions come together to form a solid lattice (this enthalpy is known as lattice enthalpy) If the solvation enthalpy is greater than lattice enthalpy, a solid will dissolve in water. Solute properties & electrolytes: dissolved ions cause the formation of solutions that can conduct electricity. Sunday, october 15, 2017: molecules that don"t break apart into ions at all are said to be non-electrolytes. Solubility rules: qualitative guidelines: ionic compounds that fully dissolve will act as strong electrolytes, always follow the lower-numbered guideline when 2 guidelines are in con ict. This leads to the correct prediction in most cases: solubility guidelines:
