To melt an ionic solid, energy must be supplied to disrupt the forces between ions so the regular array of ions collapses. If the distance between the anion and cation in a crystalline solid decreases (but ion charges remain the same), should the melting point increase or decrease? Explain your reasoning.
Calculate the concentration of IO3- in a 3.02 mM Pb(NO3)2 solution saturated with Pb(IO3)2. The Ksp of Pb(IO3)2 is 2.5 × 10-13. Assume that Pb(IO3)2 is a negligible source of Pb2 compared to Pb(NO3)
