順酐廠家告訴你氫氧化鉀乙醇溶液配置方法以及氫氧化鉀溶液儲(chǔ)存要求。氫氧化鉀的分子式為KOH,又稱苛性鉀,一種強(qiáng)堿性化工原料。常用于制取碳酸鉀(電視顯像管用玻璃和特種玻璃)、軟肥皂、清潔劑和顏料等,在電鍍、堿性電解質(zhì)蓄電池等方面也有應(yīng)用。
Maleic anhydride manufacturers tell you the preparation method of potassium hydroxide ethanol solution and the storage requirements of potassium hydroxide solution. The molecular formula of potassium hydroxide is Koh, also known as caustic potassium, a strong alkaline chemical raw material. It is often used to make potassium carbonate (glass for TV picture tube and special glass), soft soap, detergent and pigment, etc. it is also used in electroplating, alkaline electrolyte battery, etc.
配制0.1mol/L氫氧化鉀500ml步驟:(1)計(jì)算:0.1mol/L*0.5L*56g/mol=2.8g(2)稱量:稱氫氧化鉀2.8g(3)溶解:固體放入小燒杯,加少量蒸餾水溶解,用玻璃棒攪拌(4)冷卻:室溫(5)轉(zhuǎn)移:用玻璃棒引流轉(zhuǎn)入500ml容量瓶(6)洗滌:用蒸餾水洗滌燒杯,玻璃棒2-3次,洗滌液也轉(zhuǎn)入容量瓶(7)搖動(dòng):搖動(dòng)容量瓶讓溶液混合均勻(8)定容:加蒸餾水離刻度線1-2cm時(shí),改用膠頭滴管滴加蒸餾水,到平視時(shí)凹液面的切線與刻度線重合時(shí)結(jié)束。(9)搖勻:震蕩容量瓶(10)裝瓶:裝入潔凈干燥的試劑瓶,貼上標(biāo)簽。
Preparation of 0.1mol/l potassium hydroxide 500ml steps: (1) calculation: 0.1mol/l * 0.5L * 56g / mol = 2.8g (2) weighing: 2.8g potassium hydroxide (3) dissolving: put the solid into a small beaker, add a small amount of distilled water to dissolve, stir with a glass rod (4) cooling: to room temperature (5) transferring: drain with a glass rod into a 500ml volumetric flask (6) washing: wash the beaker with distilled water, glass rod 2-3 times, The washing solution is also transferred into the volumetric flask (7) shaking: shaking the volumetric flask to make the solution mix evenly (8) constant volume: add distilled water to 1-2cm away from the scale line, use a rubber tipped dropper to drop distilled water until the tangent line of concave liquid level coincides with the scale line in head up view. (9) Shake well: shake volumetric flask (10) bottling: put clean and dry reagent bottle and label.
