Raws li dilute sulfuric acid yog zoo tagnrho rau redox titration vim nws tsis yog tus neeg sawv cev oxidizing thiab tsis yog tus neeg sawv cev txo qis. HCL yog lub zog electrolyte dissociates hauv dej kom muab H + thiab Cl-ions. Li no ssome npaum li cas KMnO4 yog siv nce hauv oxidising Cl- rau Cl2. Ib sab KMnO4 yog oxidising oxalate ion rau CO2.

Tib neeg kuj nug, vim li cas h2so4 siv hauv titration ntawm KMnO4?

Sulfuric acid yog ntxiv los tiv thaiv hydrolysis thiab muab cov nyiaj seem H + ions nyob rau hauv cov tshuaj kom cov tshuaj tiv thaiv txheej txheem thiab kuj sulfuric acid yog ruaj khov rau oxidation. Los ntawm cov tshuaj tiv thaiv saum toj no nws pom tseeb tias 8 moles ntawm H + ions yuav tsum tau rau ib mole ntawm MnO4- yog li sulfuric acid muab qhov xav tau hydrogen ion.

Kuj Paub, vim li cas KMnO4 siv hauv titration? Yog li KMnO4 ua raws li nws tus kheej qhov taw qhia. Potassium Permanganate yog ib tug oxidizing tus neeg sawv cev, uas yog sib sib zog nqus violet xim. Thaum twg siv hauv redox titration , nws tau txo qis rau hauv xim av xim Mn2+ ion (hauv acidic media) ntawm qhov kawg taw tes thiab xim hloov ntawm qhov kawg taw tes tuaj yeem kuaj pom tau yooj yim.

Hais txog qhov no, vim li cas peb ntxiv Dil h2so4 hauv titration?

Sulfuric Acid ( H2SO4 ) yog siv nyob rau hauv lub redox titration txheej txheem vim nws muab cov H(+) ions tsim nyog rau cov tshuaj tiv thaiv tshwm sim sai dua thaum lub sulphate (-) ions NW nyuam qhuav tshwm sim thaum lub sij hawm cov tshuaj tiv thaiv. Yog li ntawd, sulfuric acid yog ntxiv kom cov kua qaub acidic.

Vim li cas HCl tsis siv hauv KMnO4 titration?

KMnO4 yog ib tug muaj zog oxidizing neeg sawv cev thiab nws muaj peev xwm oxidize HCl thiaj li tso cov chlorine gas, yog li ntawd HCl ua tsis tau siv ua acidify poov tshuaj permanganate daws nyob rau hauv volumetric tsom xam.
