PROSPHOROUS ACID
Phosphorous acid (H₃PO₃) yog diprotic acid, txhais tau tias nws tuaj yeem pub ob lub protons (H⁺) hauv cov kua dej. Nws nthuav tawm cov khoom txo qis, ua rau nws muaj txiaj ntsig hauv cov tshuaj tiv thaiv redox. Ib qho ntawm nws cov yam ntxwv tseem ceeb ntawm cov tshuaj yog qhov muaj PH daim ntawv cog lus, uas txawv ntawm phosphoric acid (H₃PO₄). Thaum rhuab, phosphorous acid decomposes tsim phosphine (PH₃) thiab phosphoric acid. Nws reacts nrog bases los tsim phosphite ntsev. Phosphorous acid kuj ua raws li ib tug precursor nyob rau hauv kev npaj ntawm tej yam organophosphorus tebchaw. Nws lub xeev oxidation ntawm phosphorus yog +3.

Phosphorous acid yog qee zaum siv los ua cov tshuaj phosphite chiv, uas maj mam nqus thiab siv los ntawm cov nroj tsuag. Tsis zoo li phosphate chiv, phosphites tuaj yeem nqus los ntawm nplooj, ua rau lawv muaj txiaj ntsig zoo rau foliar pub. Lawv muab ib qho kev tso tawm qeeb ntawm phosphorus uas pab txhawb kev loj hlob hauv paus, ntxiv dag zog rau cov phab ntsa ntawm tes, thiab ua kom muaj zog tiv thaiv kab mob. Vim nws cov toxicity tsawg, nws tuaj yeem siv tau zoo rau ntau hom qoob loo yam tsis muaj kev cuam tshuam rau cov av hauv ntuj microbial tshuav nyiaj li cas.
