A.
System (of partially miscible liquid pairs), in which the mutual solubility increases with rise in temperature, are said to possess an upper consolute temperature |
|
B.
Systems, in which the mutual solubility increases with decrease in temperature, are said to possess lower consolute temperature |
|
C.
Nicotine-water system shows both an upper as well as a lower consolute temperature, implying that they are partially miscible between these two limiting temperatures |
|
D.
None of these |
