Nhanganyaya
Phosphoric acid is an inorganic compound ine kemikari formula H3PO4. Inoratidzika seisina ruvara, yakajeka makristasi uye inonyungudika nyore mumvura. Phosphoric acid ine acidic uye inogona kuita nesimbi kugadzira hydrogen gasi, pamwe nekuita nedoro kugadzira phosphate esters.
Phosphoric acid inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira seyakagadzirwa kugadzirwa kwefetereza, maajenti ekuchenesa, uye zvinowedzera zvekudya. Inoshandiswawo mukugadzira phosphate munyu, mishonga, uye mumakemikari maitiro. Mu biochemistry, phosphoric acid chinhu chakakosha chemasero, kutora chikamu musimba metabolism uye DNA synthesis, pakati pemamwe maitiro ehupenyu.
Kugadzirwa kwephosphoric acid kunowanzo kusanganisa nzira dzakanyorova uye dzakaoma. Kunyorova kunosanganisira kudziyisa phosphate rock (yakadai seapatite kana phosphorite) ine sulfuric acid kuti ibudise phosphoric acid, nepo kuoma kwacho kunosanganisira kuverengerwa kwedombo rephosphate rinoteverwa nekutorwa kwemvura uye kuita ne sulfuric acid.
Mukugadzirwa kwemaindasitiri uye kushandiswa, phosphoric acid inoisa dzimwe njodzi dzekuchengetedza. Yakanyanya kuomeswa phosphoric acid inokanganisa zvakanyanya uye inogona kukonzera kutsamwa uye kukuvadza paganda uye nzira yekufema. Naizvozvo, matanho akakodzera ekudzivirira anofanirwa kutorwa kudzivirira kubata kweganda uye inhalation yehutsi hwayo kana uchibata phosphoric acid. Uyezve, phosphoric acid inoisawo njodzi kwezvakatipoteredza, sezvo kubuda kwakanyanya kunogona kutungamirira kumvura uye kusvibiswa kwevhu. Saka, kutonga kwakasimba uye maitiro ekurasa marara kwakakosha panguva yekugadzira uye kushandiswa.
