Mawu Oyamba
Phosphoric acid ndi organic pawiri ndi mankhwala formula H3PO4. Zimawoneka ngati makhiristo opanda mtundu, owoneka bwino ndipo amasungunuka mosavuta m'madzi. Phosphoric acid ndi acidic ndipo amatha kuchitapo kanthu ndi zitsulo kuti apange mpweya wa haidrojeni, komanso kuchitapo kanthu ndi mowa kuti apange phosphate esters.
Phosphoric acid imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza ngati zopangira zopangira feteleza, zoyeretsera, ndi zowonjezera zakudya. Amagwiritsidwanso ntchito popanga mchere wa phosphate, mankhwala, komanso popanga mankhwala. Mu biochemistry, phosphoric acid ndi gawo lofunikira la maselo, kutenga nawo gawo mu metabolism yamphamvu ndi kaphatikizidwe ka DNA, pakati pa njira zina zamoyo.
Kupanga kwa phosphoric acid nthawi zambiri kumaphatikizapo kunyowa komanso kuuma. Njira yonyowa imaphatikizapo kutenthetsa thanthwe la phosphate (monga apatite kapena phosphorite) ndi sulfuric acid kuti apange phosphoric acid, pamene kuuma kumaphatikizapo kuwerengetsa thanthwe la phosphate ndikutsatiridwa ndi kunyowa konyowa ndi kuchitapo kanthu ndi sulfuric acid.
Popanga mafakitale ndikugwiritsa ntchito, phosphoric acid imakhala ndi zoopsa zina zachitetezo. Kuchuluka kwa phosphoric acid kumawononga kwambiri ndipo kungayambitse kuyabwa ndi kuwonongeka kwa khungu ndi kupuma. Choncho, njira zodzitetezera ziyenera kuchitidwa kuti musagwirizane ndi khungu ndi kupuma kwa nthunzi yake pogwira phosphoric acid. Kuphatikiza apo, phosphoric acid imabweretsanso zoopsa zachilengedwe, chifukwa kukhetsa kwambiri kumatha kubweretsa kuipitsidwa kwamadzi ndi nthaka. Chifukwa chake, kuwongolera mosamalitsa ndikuchotsa zinyalala moyenera ndikofunikira panthawi yopanga ndikugwiritsa ntchito.
