Concept explainers
(a)
Interpretation:
The materials used in the making of the soap as to be identified and classified as a substance or a mixture. If it is a substance, whether it is an element or a compound as to be indicated. If it is a mixture, whether it is homogeneous or heterogeneous has to be indicated.
Concept Introduction:
Homogeneous mixture:
The mixture which consists of two or more substances that is completely uniform and the substances are in same phase (
Heterogeneous mixture:
The mixture consists of two or more substances which are visibly in different phases or a non-uniform mixture is said to be heterogeneous mixture.
(b)
Interpretation:
If fat and lye are completely transformed into soap, the mass of the soap produced has to be calculated.
(c)
Interpretation:
The physical and chemical processes that occur in the making process of the soap has to be given.
