WebVandaag · NaOH is considered as a fine catalyst for the hydrogen transfer of an extensive variety of aliphatic ketones and aromatics which can be converted to high yields corresponding alcohols. The use of NaOH is uncomplicated, nontoxic, and easy-to-handle and there are no requirements of anhydrous reagents, an inert atmosphere, or any … WebIn this experiment, the titrant NaOH is a strong alkaline and the analyte acetic acid is a weak acid. Before performing the experiment, it is important to consider the hygroscopic nature of NaOH. This property requires its solution to be standardized with a stable primary standard such as potassium hydrogen phthalate (KHC 8 H 4 O 4).
WebAs mentioned above, standard NaOH solutions cannot be prepared by weighing solid NaOH, since the reagent often contains significant amounts of impurities and is highly hygroscopic. Standard NaOH solutions are usually prepared by diluting a 50 wt% aqueous solution of NaOH to approximately the desired concentration. Web15 okt. 2024 · Potassium hydrogen phthalate. KHP is slightly acidic, and it is often used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately. It is not hygroscopic. It is also used as a primary standard for calibrating pH meters because, besides the properties just mentioned,….
