Quantitative analysis - Estimation of Elements
After qualitative analysis of elements, the another step in the determination of molecular formula of an organic compound is the estimation of several elements by mass, that is finding the percentage composition of the elements by mass. The several methods generally employed for the estimation of principal elements are as follow:
1. Carbon and Hydrogen
2. Nitrogen
3. Halogens
4. Sulphur
5. Phosphorous
6. Oxygen
Compute the percent ionic character of the interatomic bonds for the following compound: TiO2.
A water solution contains 64% Na 2 S 2 O 2 together with 1.0% soluble impurity. Upon cooling to 5°C, Na 2 S 2 O 2 ·5H 2 O. crystallizes out. The solubility of this hydrate is 1.35
The high melting point and insolubility in organic solvents of sulphanilic acid are due to its ...... structure: (1) Simple ionic (2) Bipolar
