Hydrochloric acid: physico-sinadaran Properties, da shirye-shiryen da kuma yin amfani da

Dabzar hydrochloric acid da aka yi amfani da Pharmaceutical bincike, domin warkewa dalilai da aka yi amfani da tsarma. A Jihar Pharmacopeia ne na musamman alluna da wanda ƙayyade yawan acid abun ciki na ruwa-ruwa bayani. Don yin wannan, kawai bukatar mu san ta musamman nauyi.

Amfani da wadannan alluna, za ka iya kyawawan sauki duba taro na acid bayani. Al'ada (ba m isa) acid mafita na iya zama sauri shirya ta amfani da na kowa hanyoyin. Alal misali, hydrochloric acid yana da wani musamman nauyi na 1.19, Ina nufin dauke da 37% HC1. Zaton cewa wajibi ne a shirya 100 ml na 10% acid. Don yin haka, yi daidai gwargwado: a kowane 100 sassa da nauyin samuwa HC1 dauke 37 sassa na hydrogen chloride. Saboda muna bukatar shirya wani 10% bayani, ya kamata dauke da goma sassa da mutum ɗari nauyi sassa na bayani.

Saboda haka, a cikin wannan yanayin X - shi ne mai daraja wanda zai nuna nawa ya dauki sassa da nauyin kashi 37 cikin dari warware, diluting da ruwa zuwa 100 sassa da nauyi, to samu 10% bayani:

100-37

X-10

X = 100 * 10/37 = 27 sassa da nauyi.

Hydrogen chloride - quite mai guba abu wanda zai iya sa tsanani konewa kazalika da dukan kwayoyin yawan guba. Kamar yadda wani maganin guba domin guba HC1 amfani magnesia. Don shafe acid na iya ma za a yi amfani da da kuma soapy ruwa, fesa dabba gawayi, madara, daban-daban Yanã rufe garkensu.

Maye acid ta bakin kamata ba za a wajabta emetics, kazalika da yin amfani da miyagun ƙwayoyi a ciki dauke da Carbonated Alkali. Idan guba ciki da aka wanke da copious yawa na ruwa tare da wani bincike. Good sakamakon da samu ta ƙara ruwa zuwa magnesium oxide kazamta. A gaban waje konewa acid, likitoci bayar da shawarar a wurin da shan kashi na dogon lokaci zuwa wanke da ruwa. Filin ƙona da karkara aka tsarkake tare da tsarki ethanol sa'an nan gabatar da wani slurry na sodium bicarbonate, kuma a saman da shi - barasa gauze.

Hydrogen chloride ne daidai narkewa a cikin ruwa. A 0 C ͦ daya girma na ruwa dissolves da ɗari kundin na gas. A magani, masana'antu da kuma ko da a cikin kasa tattalin arzikin da aka sosai sau da yawa amfani hydrochloric acid. Its dabara aka wakilta hydrogen da Halo - C1.

HC1 Tattalin a cikin na asali sinadaran masana'antu hlorovodorodistogo na gas tunawa da ruwa. Chloride, hydrogen da aka samar ta hanyar maida martani sulfuric acid tare da sodium chloride.

tsarki ya tabbata a Test

Akwai wasu bukatun:

- hydrochloric acid a cikin abun da ke ciki ba ya dauke da nauyi karfe salts, nitric, nitrous da sulphurous acid, free chlorine da arsenic.

- izini kawai bai isa a kula burbushi na baƙin ƙarfe salts, free C1 impurities za a iya bude ta dauki: C12 + 12 + 2K1-2KS1.

- domin tabbatar da dalilin da impurities na sulfurous acid shirya bayani na aidin a potassium iodide nuna alama - sodium sitaci da blue color daga cikin bayani a gaban sulphurous acid da aka bleached cikin dakika 30

- gagarumin saura a kan danshin 10 grams na acid kada wuce kashi 0.01 (ma'adinai impurities).

A gwada yawa analysis za'ayi da titration da sodium hydroxide bayani a gaban methyl orange nuna alama. HC1 yarda abun ciki a cikin acid 24,8-25,2%.

Hydrochloric acid ne kunshe a cikin abun da ke ciki da kuma nazarin halittu ruwaye. Alal misali, a ciki ruwan 'ya'yan itace, ta maida hankali ne har zuwa 0.5%, yana taimaka wa karya saukar da sunadarai. Tsarma HC1 (8.2%) a lokacin gudanar da baxini activates hira da pepsinogen (proenzyme) a cikin pepsin, kara habaka da secretory aiki na pancreas, inganta da motsi na ciki abinda ke ciki da hanjinsu. Yana farfado wani antibacterial sakamako dangane da vegetative da kuma spore microflora. Wannan acid da aka gudanar da baki ga rage acidity, domin tsotsa da magani daga baƙin ƙarfe rashi anemia.
