Why melting point of LiCl is lower than NaCl?
Using polarizing theory: Li+ has a smaller atomic radius than Na+. However they both have the same charge, +1. The Cl- is identical in both compounds, and has a large electron cloud surrounding it. Using the equation for static force: F=kq1q2/r2 where k is Coulomb's constant, q1 is the charge of the Li+ or Na+ cation, q2 is the charge of an electron in the chlorine electron cloud, and r is the distance between the chlorine electron and the Li+ or Na+ nucleus. we see that the force increases with a smaller radius r. Since the Li+ ion is smaller, the chlorine electrons are closer to the nucleus, and thus these electrons are drawn even closer to the Li+ nucleus. All together, the electrons from the chlorine in LiCl are pulled around the Li+ ion to a much further extent than they are pulled around the Na+ in NaCl. Therefore the bond in LiCl has a much more covalent character than NaCl. Bond polarity is also reduced, since the electrons are not spending all of their time around the Cl-. Since the LiCl molecules are less polar than NaCl, there are less electrostatic forces holding them together in a solid crystal lattice. Therefore the energy required to loosen the molecules from a crystal to a liquid is less for LiCl than NaCl. Finally we come to the conclusion that therefore, the melting temperature of LiCl must be lower than NaCl
Write NaCl plus AgC2H3O2 equals NaC2H3O2 plus AgCl as an net ionic equation?
Na+(aq) + C2H3O2-(aq) + Ag+(aq) + Cl-(aq) → Na+(aq) + C2H3O2-(aq) + AgCl(s) This net ionic equation represents the reaction between sodium chloride and silver acetate, forming sodium acetate and silver chloride.
How do you find molar conductivity of nacl at infinite dilution when given molar conductivities at infinite dilution of licl nano3 and lino3?
Molar conductivity = the sum of the ion conductivities of cation and anion at infinite dilution, such that : This behavior was explained by Kohlraushc's law of independent migration of ions. So you can look this law up for further explanation
