Answer / kabeer
As it has 4 double bonds,the primery requiremnt to detect
the compount by uv in its structure, that absorbs uv light,
and gives a clear spot. and that can tell us that wether
our cabinet is detectiong the spots properly by emissing
the selected wavelenghts or not.

Sodium salicylate has 4 double bonds in its structure.due to this conjugated double bond structure it shows clear spot in shorter wavelength(254nm)and longer wavelength(365nm) during UV cabinet calibration for TLC.

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
