For standardization of volumetric solutions, acceptance limit for concentration is considered as 10% of nominal concentration and %RSD as NMT 0.2% (for appropriate no. of replicates). But , if %RSD has not met, what should be further action?21
please explian me about area normalisation method,diluted standard method,impurity vs impurity and which one has to be selected in method development
What is the formula to determine the concentration of M of a solution given the % transmittance? Use %T = 43.7 as an example.
In IR spectra, generally a molecule vibrates without apply emr or ir light?

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.
