kbr is one of the compounds which donot absorb the provided
radiations of "IR" and hence donot exhibit its absorption
pattern in the graph.........&&&&&&&

:
kbr only to make sure that the sample stands correctly and
its uniformly distributed in the pellet

we are performed SOR for a particular product the limit is -6 to -10.We face particular bathes it is not meeting the specification.we performed diffrent instrument diffrent analyst we are getting diffrent diffrent results.solvent is dimethyl sulfoxide what could be the reasion

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.
