Qhov sib txawv tseem ceeb ntawm Caro's acid thiab Marshall's acid yog Caro's acid muaj ib pawg sulfate, whereas Marshall's acid muaj ob pawg sulfate.

Caro's acid thiab Marshall's acid yog inorganic acid compounds uas muaj sulfate pawg. Lawv muaj npe raws li peroxymonosulfuric acid thiab peroxydisulfuric acid, feem. Raws li cov npe no, cov tshuaj inorganic muaj cov pab pawg peroxide thiab sulfate pawg ua ke; Cov pab pawg sulfate hauv peroxydisulfuric acid txuas nrog los ntawm pawg peroxide.

Caro's Acid yog dab tsi?

Caro's acid yog ib qho inorganic acid uas muaj ib pawg sulfate thiab ib pawg peroxide. Peb tuaj yeem hu nws li peroxymonosulfate acid vim nws muaj ib pawg peroxide thiab ib pawg sulfate. Cov tshuaj formula ntawm no compound yog H₂SO₅ Nyob rau hauv cov compound no, cov sulfur atom nyob rau hauv nruab nrab thiab nws muaj ib tug tetrahedral geometry. Peb tuaj yeem qhia qhov kev sib txuas ntawm cov atoms li HO-O-S(O_2)-OH.

Qhov txawv tseem ceeb - Caro's Acid vs Marshall's Acid

Caro's acid yog ib qho muaj zog oxidant thiab nws yog qhov tawg heev. Tus kws tshawb fawb Heinrich Caro, 1898 pom cov kua qaub no, yog li nws tau muab npe rau nws. Thaum xav txog kev tsim cov kua qaub no, hauv cov txheej txheem kuaj, peb xav tau chlorosulfuric acid thiab hydrogen peroxide. Thaum tsim tawm, nws zoo nkaus li dawb crystals. Cov molar loj ntawm cov compound yog 114 g / mol.

Nyob rau hauv nam ntawm kev siv, cov kua qaub no yog siv los ntxuav thiab tua kab mob. Piv txwv li, kev kho dej hauv pas dej da dej kom tshem tawm cov kab mob. Tsis tas li ntawd, ammonium ntsev ntawm cov kua qaub no muaj txiaj ntsig zoo hauv kev lag luam yas, raws li polymerization pib. Nws tseem yog ib qho tseem ceeb ua tus neeg sawv cev oxidizing.

Marshall's Acid yog dab tsi?

Marshall's acid yog ib qho inorganic acid uas muaj ob pawg sulfate thiab ib pawg peroxide. Cov tshuaj formula ntawm no compound yog H₂S₂O₈ Nws tau txais nws lub npe los ntawm tus kws tshuaj. Hugh Marshall, uas tau pom qhov sib xyaw no. Peb tuaj yeem muab lub npe no ua cov tshuaj peroxydisulfuric acid vim tias muaj ob pawg sulfate. Ntxiv mus, peb tuaj yeem sau cov qauv qauv ntawm qhov sib xyaw no li HO₃S-O-O-SO_3H.

Qhov sib txawv ntawm Caro's Acid thiab Marshall's Acid

Peb tuaj yeem npaj cov tshuaj no siv cov tshuaj tiv thaiv ntawm chlorosulfuric acid hydrogen peroxide. Peb tuaj yeem tsim nws los ntawm electrolysis ntawm sulfuric acid (concentrated acid) siv platinum electrodes. Ntawm no, peb yuav tsum siv lub siab voltage thiab. Thaum xav txog kev siv Marshall's acid, nws yog qhov tseem ceeb tshaj plaws los ua tus neeg sawv cev oxidizing muaj zog.

Qhov txawv ntawm Caro's Acid thiab Marshall's Acid yog dab tsi?

Caro's acid thiab Marshall's acid yog ib qho tseem ceeb inorganic acids uas muaj sulfate pawg. Qhov sib txawv tseem ceeb ntawm Caro's acid thiab Marshall's acid yog Caro's acid muaj ib pawg sulfate, thaum Marshall's acid muaj ob pawg sulfate. Lub npe tshuaj ntawm Caro's acid yog peroxysulfuric acid, thaum lub npe tshuaj ntawm Marshall's acid yog peroxydisulfuric acid.

Ntxiv mus, ob qho tib si cov ntsiab lus tseem ceeb yog cov muaj zog oxidizing cov neeg ua haujlwm. Tab sis, ntxiv rau nws, Caro's acid kuj tseem siv tau los ua tus neeg saib xyuas thiab tshuaj tua kab mob. Dhau li ntawd, peb tuaj yeem sau cov qauv qauv ntawm Caro's acid li HO-O-S(O₂)-OH, thiab cov qauv qauv ntawm Marshall's acid yog HO _{3 S-O-O-SO}3_H.

Hauv qab infographic qhia txog qhov sib txawv ntawm Caro's acid thiab Marshall's acid.
