Textbook Question
Chapter 9, Problem 9.99GP
To prevent accumulation of ice on roads and sidewalks, many municipalities (and home-owners) will apply de-icing compounds to “melt” the ice by lowering the freezing point.
(a) Obtain a package of de-icing compound/mixture and identify the ingredients or look up the composition. Are the compounds ionic or molecular? Discuss possible reasons for the use of these compounds and for the specific compounds used in the formulations.
(b) Some de-icing compositions include dyes or colored compounds called indicators. Why?
