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.
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.
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
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.
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.
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

Brook field viscometer is a type of volitional viscometer. It contains different size violating spindle which is immersed in the test material to be tested.
The stalagmometer is consist of a capillary bore with a bulb at the middle. The surface tension of the given liquid can be determined by using the following formula.
The stalagmometer consist of a glass capillarytube with a bulb at the middle.There is a capillary bore at the tip of the stalagmometer.
