Dilute sulfuric acid muaj water Cov ions tam sim no hauv qhov sib tov yog H ⁺ thiab OH ^{-(los ntawm dej) thiab H} + ^{thiab SO} 4₂^- los ntawm sulfuric acid. Lub H ^{+ions yog nyiam mus rau cathode thiab ob qhov tsis zoo ions tau nyiam rau lub anode tab sis nws yog OH} -^{ion uas poob electrons.}

Yuav ua li cas thaum dilute h2so4 Electrolysed?

Thaum lub sijhawm electrolysis ntawm dilute aqueous sulfuric acid, siv platinum electrodes, oxygen gas yog liberated ntawm anode. Li no, qhov kev xaiv B) oxygen yog cov lus teb raug. Lus Cim: Cathode yog qhov tsis zoo electrode. … Ntawm cathode, protons tau tawm los ua cov pa roj hydrogen.

Lub luag haujlwm ntawm dilute sulfuric acid hauv electrolysis yog dab tsi?

sulfuric acid yog dej sib tov los qhia ions hauv nwsyog li cov dej ua kom nce ntxiv uas ua rau cov tshuaj tiv thaiv sai dua. Txawm li cas los xij nws tsis cuam tshuam rau cov tshuaj muaj pes tsawg leeg ntawm cov tshuaj reactant lossis cov khoom, nws tsuas yog ua kom nrawm ntawm cov tshuaj tiv thaiv.

Vim li cas cov roj hydrogen tso tawm thaum dilute sulfuric acid yog Electrolysed?

Cov ions no yog tsim thaum ib feem me me ntawm cov dej molecules lawm dissociate. Yog hais tias dej yog acidified nrog me ntsis dilute sulfuric acid: H ^{+ions yog attracted rau cathode, nce electrons thiab tsim hydrogen gas}.

Yuav ua li cas thaum dilute sulfuric acid yog electrolysed ntawm inert electrodes?

13 Dilute sulfuric acid yog electrolysed ntawm inert electrodes. … 1 Hydrogen tso tawm ntawm qhov tsis zoo electrode. 2 Oxygen tso tawm ntawm qhov zoo electrode. 3 Sulfur dioxide tso tawm ntawm qhov zoo electrode.
