physical chemistry - Why calcium chloride is used to …

Explain why one mole of $\ce{CaCl2}$ would be more effective than one mole of $\ce{NaCl}$. So from everything I''ve learned, $\ce{NaCl}$ would be more effective for the melting , because calcium chloride dissociates into three ions and sodium chloride dissociates into two, so that would make the boiling point of water with calcium chloride higher.
