Using your instruction of colligative properties interpret whether sodium chloride or calcium chloride would be a further efficient material to dissolve the ice on a silken sidewalk. Use 3 – 4 sentences in your description.
Expert Repartee
Abstracted of sodium chloride or calcium chloride would decreases the freezing subject-matter. gone the freezing subject-matter of inspire is 0 deg.
we perceive delta Tf= i. Kf . m where m molality; i vandewal coefficient.
if i prize is further dippression in freezing subject-matter conquer be further
coercion NaCl i=2 (na+ and cl-); coercion CaCl2 i=3 (Ca+2 and 2Cl-).
Cacl2 abstracted conquer inferior the freezing subject-matter to further distance than NaCl.
But Calcium chloride effects an exothermic reaction when partial with ice, which resources that it literally heats up when it comes in adjunction with ice and heats up ice. so Calcium chloride is used in the dissolve the ice on a silken sidewalk.
Repartee : Calcium Chloride
Sodium chloride does not attributable attributable attributable effect any exothermic reaction.
