Rau balance HBr + Ba(OH)2 = BaBr2 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug.

Ntawm no, koj yuav ua li cas neutralize hydrobromic acid?

1 Teb

  1. Lub hydrobromic acid neutralizes calcium carbonate nyob rau hauv ib tug ob peb hloov cov tshuaj tiv thaiv. Cov khoom yog calcium bromide thiab carbonic acid.
  2. Cov carbonic acid tsis ruaj khov. Nws decomposes tsim carbon dioxide thiab dej.
  3. Cov tshuaj tiv thaiv yog qhov sib npaug ntawm ob qhov sib npaug saum toj no. 2HBr + CaCO3 → CaBr2 + H2O + CO2

Tsis tas li ntawd, qhov sib npaug tshuaj sib npaug rau cov tshuaj tiv thaiv acid ntawm hydrobromic acid nrog sodium hydroxide yog dab tsi? A) NaOH (aq) + HBr(aq) → H2O(l) + NaBr(aq) B)

Tsis tas li ntawd, hydrobromic acid siv rau dab tsi?

Hydrobromic acid yog mas siv rau Kev tsim cov inorganic bromides, tshwj xeeb tshaj yog cov bromides ntawm zinc, calcium, thiab sodium. Nws yog ib qho tseem ceeb reagent rau tsim organobromine tebchaw. Qee cov ethers yog cleaved nrog HBr. Nws kuj catalyzes alkylation cov tshuaj tiv thaiv thiab tshem tawm ntawm qee yam ores.

Dab tsi yog cov tshuaj formula rau hydrobromic acid suav nrog theem?

Hydrobromic acid yog qhov kev daws teeb meem ntawm hydrogen bromide ( HBr ) nyob rau hauv dej, thiab muaj zog ntxhia kua qaub . Formula thiab qauv : Cov chemical formula ntawm hydrobromic acid (aqueous hydrogen bromide ) yog HBr , thiab nws cov molar loj yog 80.9 g / mol.
