3. Kuziva Zviri MuCalcium Formate
3.1 Ongororo yeMaitiro eCalcium Formate: Mumhinduro yecalcium formate ine alkaline zvishoma, wedzerai potassium permanganate yakawandisa. Pisai kuti muve nechokwadi chekuti oxidation reaction inopera. Potassium permanganate yakawandisa ichaburitsa iodine kubva kupotassium iodide mumhinduro ine acidic, iyo inozoiswa titration ne sodium thiosulfate standard solution.
3.2 Matanho Ekuona Calcium Formate: Yera inenge 0.4g ye calcium formate sample (yakarurama kusvika 0.0002g), iise mu 250ml volumetric flask, inyungudise mumvura, isa mvura kusvika pachiratidzo, wozunza zvakanaka. Pipette 25.00ml (kana 10ml) yemushonga uyu mu flask ye iodine, wedzera 0.2g ye anhydrous sodium carbonate, wozunza zvakanaka. Wedzera nemazvo 50.00ml (kana 20ml) ye potassium permanganate standard solution, pisa mumvura yekugeza kwemaminitsi makumi matatu, wozoitonhodza. Wedzera 6ml ye sulfuric acid solution uye 2g ye potassium iodide, rega zvimire murima kwemaminitsi mashanu. Isa sulfate ne sodium thiosulfate standard solution; pedyo ne endpoint, wedzera 3ml ye starch indicator (0.5%), uye ramba uchizunza kusvika ruvara rwebhuruu rwapera. Ita bvunzo isina chinhu panguva imwe chete.

Tsvaga mabhenefiti asingakundike ecalcium formate—wedzera mashandiro echigadzirwa chako uye deredza mitengo! Unoda kuziva zvakawanda here? Dzvanya kuti ubvunze izvozvi kuti uwane mhinduro dzakagadzirirwa iwe!
