Kev daws teeb meem Acid-Base Neutralization

  1. Kauj ruam 1: Xam tus lej ntawm moles ntawm OH-. Molarity = moles/ ntim . moles = Molarity x Ntim . moles OH- = 0.02 M / 100 ml.
  2. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau . Molarity = moles/ ntim . Ntim = moles/molarity. Ntim = moles H+/ 0.075 Molarity.

Ib yam li ntawd, nws yog nug, ua li cas koj neutralize lub hauv paus muaj zog?

Siv ib tug qaug zog acid rau neutralize puag . Piv txwv xws li sodium hydroxide, potassium hydroxide, thiab ammonia. Muaj ntau yam khoom sib txawv pab hauv lub neutralization ntawm acids thiab hauv paus . Lawv tuaj yeem ua tau yooj yim li ib lub hnab ntawm citric acid lossis sodium sesquicarbonate, los yog ua haujlwm raws li cov khoom siv thiab cov khoom nruab nrab ua ke.

Tsis tas li ntawd, nws puas siv ntau lub hauv paus los ua kom cov kua qaub muaj zog? Muaj zog acids yuav neutralize lub hauv paus muaj zog ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug. Ntau ntim ntawm qaug zog kua qaub yog xav tau neutralize lub hauv paus muaj zog yog hais tias cov concentrations sib npaug thiab vise versa rau qaug zog hauv paus thiab muaj zog acids . Ib qho tsis yog ib qho kev daws teeb meem uas muaj qhov tsis muaj zog kua qaub thiab ntsev nrog tib lub anion li tus kua qaub.

Yog li ntawd, yuav tsum muaj pes tsawg moles ntawm NaOH kom tsis txhob muaj cov kua qaub?

1 Teb. Koj xav tau 3 mol ntawm sodium hydroxide rau neutralize 1 mol ntawm phosphoric kua qaub.

Thaum ua cov tshuaj acidic yooj yim Yuav ua li cas qhov no yuav ua tau?

Ntxiv ib kua qaub nce qhov concentration ntawm H3O+ ions nyob rau hauv daws . Ntxiv ib puag txo qhov concentration ntawm H3O+ ions nyob rau hauv daws . Ib kua qaub thiab a base yog zoo li chemical opposites. Yog ib puag yog ntxiv rau ib kua qaub , cov daws ua tsawg acidic thiab tsiv mus rau nruab nrab ntawm lub pH nplai.
