A) \[CaC{{l}_{2}}\]is less soluble in \[{{H}_{2}}O\] than \[NaCl\]
B) \[CaC{{l}_{2}}\] is hygroscopic but \[NaCl\]is not
C) Eutectic mixture of \[CaC{{l}_{2}}/{{H}_{2}}O\] freezes at \[-55{}^\circ C\] while that of \[NaCl/{{H}_{2}}O\] freezes at \[-18{}^\circ C\]
D) \[NaCl\] makes the road slipperty but \[CaC{{l}_{2}}\] does not
Correct Answer: C
Solution :
[c] Due to much lower freezing point of eutectic mixture of \[CaC{{l}_{2}}/{{H}_{2}}O\].You need to login to perform this action.
