Day 5 Pre-Class Podia Problem: Melting Points of Salts

This Podia problem is based on today’s pre-class material; working through that material will help you solve the problem.

The formulas and melting points of four salts are listed below. All four compounds have the same crystal lattice as NaCl. Write a clear, concise explanation of the differences in melting points using scientifically appropriate language and including any relevant data.

NaF 996 °C         NaCl 801 °C         KCl 770 °C         CaO 2572 °C

Two days before the next whole-class session, this Podia question will become live on Podia, where you can submit your answer.
