In the technique of recrystallization, what is the 'mother liquor'? The mother liquor is the product in its liquid form. The mother liquor is always the non-limiting reactant in the reaction. The mother liquor is the filtrate. The mother liquor always refers to ethanol.

In the technique of recrystallization "the mother liquor is the filtrate".

Option: C

Explanation:

The portion of a solution remaining over after crystallization is understood as a mother liquor. It is found in chemical reactions that include sugar refining. It is the liquid produced by filtration of the crystals. The residual liquid, once the crystals have been extracted out as the mother liquor will include a portion of the initial solution as estimated at that temperature by its solubility as well as any unfiltered contaminants. Second and third crystal crops can then be collected from the mother's liquor.
