Partition co-efficient of Benzoic Acid in Benzene and Water
BACKGROUND Benzoic Acid Aim: To determine the partition co-efficient of …
Determination of Glident Efficiency
To study the effect of glident on angle of repose and to determine glident efficiency from flow rate.
Determination of specific surface area
The surface area of the powder can be calculated by using particle size data. This specific surface area may be defined as the surface area
Determination of pKa value by Half Neutralization/ Henderson Hasselbalch equation
The mixture acts as a buffer solution. During the course of titration acid concentration decreases and salt concentration goes on increasing. During any stage of titration the pH of buffer solution is explained by the Henderson –Hasselbalch equation.
Determination of viscosity of liquid using Ostwald viscometer
Ostwald viscometer is use to determine viscosity of Newtonian fluid. When the liquid flow by gravity time required for the liquid to pass between two mark A and B through the capillary tube is determined.
Determination of Freundlich and Langmuir Constants using Activated charcoal
Adsorption is a surface phenomenon. In adsorption process the adsorbate is adhered to the surface of adsorbent. Freundlich studied adsorption of gas on solid and from the experimental data gave the equation
Determination of stability constant and donor acceptor ratio of PABA-Caffeine complex by solubility method
Few properties of complexes like solubility, light absorption, conductance, partitioning behavior, chemical reactivity and conductance etc are different from their components. Example- PABA and caffeine form complexes in solution.
Partition co-efficient of Iodine in Distilled water and Carbon tetrachloride
When a solute is shaken with 2 immiscible solvents it gets partitioned between the solvents. To establish the partition co-efficient of iodine in distilled water (d.w.) and carbon tetrachloride.
Determination of critical solution temperature (CST) of phenol-water system
When small quantity of phenol is mixed with water and the mixture is shaken, phenol dissolves, forming a single layer. On adding larger quantities of phenol, however, two kinds of compositions (layers) of liquid are formed
