Explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. Why is NaCl described as a strong electrolyte? How does salt affect the boiling point of water? (in simple words) ...
The quantity of ice-melt compound needed to lower the freezing point of ice to the eutectic temperature is called the “eutectic concentration.” At this lowest temperature, the rate at which ice melts is very slow. When this melting action slows, adding more compound has no impact on lowerin...
