1Why is AgCl insoluble and NaCl soluble in water?Last time we concluded:AgCl has a significantly larger enthalpy of solvation than NaCl due to a larger lattice energy.Use the following data to explain why AgCl has a larger lattice energy than NaCl.Species Electro-negativityIonic RadiusPredicted Bond Length*ActualBond LengthNa+0.9102 pmAg+1.9115 pmCl–3.0181 pmNaCl283 pm282 pmAgCl296 pm278 pm*Predicted Bond Lengths = Sum of the Ionic Radii2Compared to NaCl, AgCl has the larger lattice energy, which means a stronger bond in Ag-Cl, because _______(A) AgCl is an ionic compound and NaCl is not.(B) The AgCl ions have larger charges so the attraction is greater.(C) The ionic radius of Ag+is larger so the electrons can reach out more strongly.(D) AgCl has more covalent character.(E) NaCl has more covalent character.What is your hypothesis?Evidence:(1) (Cl) –(Ag) = 1.1 (ionic cmpds>1.9)(2) AgCl bond length < sum of ionic radii, indicating bond is stronger and not 100% ionic
