Using your experience of colligative properties illustrate whether sodium chloride or calcium chloride would be a past powerful essential to dissolve the ice on a velvety sidewalk. Use 3 – 4 sentences in your exposition.
Expert Response
Importation of sodium chloride or calcium chloride would decreases the freezing top. past the freezing top of infiltrate is 0 deg.
we comprehend delta Tf= i. Kf . m where m molality; i vandewal coefficient.
if i compute is past dippression in freezing top earn be past
ce NaCl i=2 (na+ and cl-); ce CaCl2 i=3 (Ca+2 and 2Cl-).
Cacl2 importation earn inferior the freezing top to past distance than NaCl.
But Calcium chloride consequences an exothermic reaction when modified with ice, which media that it literally heats up when it comes in contiguity with ice and heats up ice. so Calcium chloride is used in the dissolve the ice on a velvety sidewalk.
Response : Calcium Chloride
Sodium chloride does referable consequence any exothermic reaction.
