is khp hygroscopic

Select the subject and enter the information below. 448 West Fork Drive It also serves as a thermal standard in thermogravimetric analysis[6]. It is water soluble and available in high purity. This procedure is called standardizing the NaOH solution. For the latter, benzoquinone is suggested. 4(abbreviated KHP), is a non-hygroscopic, crystalline, solid that behaves as a monoprotic acid. We offer products with the tightest specifications in the industry to make your work easier. Potassium Hydrogen Phthalate (KHP) is a classic primary standard substance in that it is readily available in high purity; is relatively inexpensive; is easy to dry; is neither hygroscopic, oxidized by air, nor affected by Carbon Dioxide (thus making it easy to weigh out); does not undergo decomposition during storage; has a relatively high equivalent weight (thus reducing errors when weighed to 0.1 mg precision); is readily soluble in water; and is stoichiometric and instantaneous in reactions. It is water soluble and available in high purity. 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. Locate your product information quickly and efficiently. ... A KHP sample of known mass (and, therefore, known moles) can be titrated with the NaOH solution to determine very precisely the concentration of the NaOH. With our robust quality system, extensive product line and custom capabilities, RICCA Chemical Company has everything you need! KHP can be used as a buffering agent in combination with hydrochloric acid (HCl) or sodium hydroxide (NaOH) depending on which side of pH 4.0 the buffer is to be. Potassium hydrogen phthalate. For the state in East Asia which is abbreviated as КНР in Russian, see, InChI=1S/C8H6O4.K/c9-7(10)5-3-1-2-4-6(5)8(11)12;/h1-4H,(H,9,10)(H,11,12);/q;+1/p-1, InChI=1/C8H6O4.K/c9-7(10)5-3-1-2-4-6(5)8(11)12;/h1-4H,(H,9,10)(H,11,12);/q;+1/p-1, Except where otherwise noted, data are given for materials in their, Smalley, I.J.,Lill,G.O.,Bentley,S.P.,Wood,D.R. 877-24-7. Thermogravimetry of potassium hydrogen phthalate and its use as a thermal standard. Phthalic acid monopotassium salt Solid NaOH is highly hygroscopic (it absorbs water from the air) and thus it cannot be accurately weighed. Because of its high purity, you can determine the number of moles of KHP directly from its mass and it is referred to as a primary standard. Solutions of NaOH react with carbon dioxide from the air. Because of its high purity, you can determine the number of moles of KHP directly from its mass and it is referred to as a primary standard. It is also used in the quality control of Potassium Hydroxide and Sodium Hydroxide solutions, and in the standardization of Perchloric Acid in Glacial Acetic Acid. Potassium Hydrogen Phthalate (KHP) is a classic primary standard substance in that it is readily available in high purity; is relatively inexpensive; is easy to dry; is neither hygroscopic, oxidized by air, nor affected by Carbon Dioxide (thus making it easy to weigh out); does not undergo decomposition during storage; has a relatively high equivalent weight (thus reducing errors when weighed to 0.1 mg precision); is … It is not hygroscopic. Monopotassium phthalate. We’ve delivered innovative products, uncompromising quality, and the tightest tolerances in the industry for over 45 years. After double-checking other sources, that I added as references to this article, it is clear that KHP is in fact not hygroscopic, or hygroscopic …
