Concept explainers
(a)
Interpretation:
The fraction of chloride content in sample
Concept Introduction:
Chemical analysis is of two types: qualitative and quantitative. It gives the stoichiometry of constituent elements in a mixture or compound which basically depends upon the physical and chemical properties.
(a)
Explanation of Solution
Sample
Molar mass of
Mass of one mole of
Then, mass of chlorine in one mole of
Fraction of chlorine present in both the samples can be calculated as given below.
Therefore, the fraction of chloride content in sample
The samples can not be distinguished by means of chemical analysis. Because both
(b)
Interpretation:
The two X-ray diffraction results has to be interpreted in terms of the structures of the crystal lattices of sample
(b)
Explanation of Solution
In case of sample
In case of sample
(c)
Interpretation:
The chemical formula for sample
(c)
Explanation of Solution
The sample
From the X-ray diffraction studies, it has decided that two salts have been chemically reorganized into a new crystal. Hence, the chemical formula for sample
