why we have to store the pH electrode in 4.01 buffer ?
Answer Posted / ashok maduri
Always keep your pH electrode moist. We recommend that you store your electrode in storage solution. If
storage solution is not available, use either a pH 4 or 7 buffer solution. DO NOT store electrode in
distilled or deionized water this will cause ions to leach out of the glass bulb and render your electrode
useless.
After storage, you may notice white KCl crystals forming outside your electrode. This will not interfere
with measurements. Simply rinse the electrode and blot dry before use.

In BP2013, Loperamid HCl monograph. Assay by titration with 0.1N sodium hydroxide using hydrocloric acid 0.01N and reading the volume added between the 2 points of inflexion. I have a question that if the diluent solvent is ethanol is certainly consumed a amount of volume of titrant, so this volume must be eliminated on the result calculation or not apart from first point which is subtracted above.

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.
