Hauv daim vis dis aus no peb yuav sib npaug qhov sib npaug KOH + H2SO4 = K2SO 4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. KOH + H2SO4 = K2SO 4 + H2O Koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab tshuaj sib npaug.

Xav txog qhov no, qhov sib npaug sib npaug rau h2so4 thiab Koh yog dab tsi?

Chemical Equation Balancer H2SO4 + KOH = K2SO4 + H2O.

Kuj Paub, qhov sib npaug sib npaug rau Koh h3po4 yog dab tsi? Tshuaj Kev sib npaug Balancer KOH + H3PO 4 = K3PO4 + H2O.

Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog cov khoom ntawm cov tshuaj tiv thaiv nruab nrab ntawm h2so4 thiab Koh?

Neutralization cov tshuaj tiv thaiv . Ob moles ntawm poov tshuaj hydroxide , lub hauv paus muaj zog, ntawm tshuaj tiv thaiv nrog ib tug mole ntawm muaj zog acid, sulfuric acid , tsim poov tshuaj sulfate thiab dej. Ib mole KOH reacts nrog ib nrab mole ntawm H2SO4 H 2 S O 4.

Yuav ua li cas thaum sulfuric acid reacts nrog poov tshuaj hydroxide?

Potassium hydroxide reacts nrog sulfuric acid Hauv cov txheej txheem uas tuaj yeem piav qhia los ntawm qhov sib npaug: 2KOH + H2SO4 K2SO4 + 2 H2O Yog tias 425 mL ntawm 0.440M H2SO4 reacts nrog 450 mL ntawm 0.210M KOH , dab tsi yog qhov concentration ntawm H2SO4 tshuav tom qab lub tshuaj tiv thaiv ua tiav?
