Web一物質含一當量所需要的質量，稱為此物質之當量重。 分別來說，首先，以酸鹼中和反應為第一例：一摩爾的H2SO4為兩當量，因為它在反應中提供兩摩爾的氫離子。 它的當量重(49.04)為它的分子量(98.07)的一半。 [1] 其次，以KMnO4的氧化還原為第二例：當KMnO4被用以氧化足量As4O6時，一摩爾的KMnO4為五當量。 這是因為一摩爾的KMnO4與5 … Web27 mrt. 2024 · The equivalent mass of Ca 2+ is its atomic mass divided by 2 as the Calcium charge is 2+. The atomic mass of calcium is about 40.1 g/mole, so its equivalent mass is 40.1/2 = 20.05 g/equiv. The milliequivalent mass is its equivalent mass expressed in mg, so the milliequivalent mass of Ca 2+ is 20.05 mg.

Potassium Permanganate KMnO4 - PubChem

WebLa méthode traditionnelle de mesure des matières organiques (DCO) est une oxydation au permanganate de potassium et son résultat est exprimé en mg/L de KMnO4. The traditional measurement of organics (COD) in natural water uses the potassium permanganate oxidation method, and its result is expressed in mg/L as KMnO4. WebSodium periodate (NaIO 4 ), is a strong oxidizing agent mainly used for the oxidative cleavage of 1,2-diols (vicinal diols) forming aldehydes and ketones depending on the structure of the alcohol.
