Teeb meem Titration Step-by-Step Solution

1. Kauj Ruam 1: Txiav txim siab [OH^-]
2. Kauj Ruam 2: Txiav txim seb tus naj npawb ntawm moles ntawm OH^-
3. Kauj Ruam 3: Txiav txim seb tus naj npawb ntawm moles ntawm H⁺
4. Kauj Ruam 4: Txiav txim siab qhov concentration ntawm HCl.
5. Teb.
6. M _{kua qaub} V _{kua qaub} = M _puag V _puag

Los ntawm qhov ntawd, koj ua li cas cov kua qaub titration titration?

Titration txheej txheem

1. Yaug lub burette nrog cov txheej txheem daws teeb meem, lub raj xa dej nrog cov tshuaj tsis paub, thiab lub khob ntim nrog cov dej sib xyaw.
2. Muab qhov ntsuas ntsuas qhov ntsuas qhov tseeb rau hauv lub khob Erlenmeyer siv lub pipette, nrog rau ob peb tee ntawm qhov taw qhia.

Kuj Paub, koj yuav suav qhov concentration ntawm cov kua qaub los ntawm qhov nkhaus titration li cas? Faib Moles los ntawm Volume Faib tus naj npawb ntawm moles ntawm cov tshuaj ntsuam xyuas tam sim no los ntawm qhov qub ntim ntawm qhov ntsuas. Piv txwv, yog tias thawj qhov ntim ntawm qhov tshuaj ntsuam yog 500 mL, faib los ntawm 1000 mL rau L kom tau 0.5 L. Sib faib 0.01 moles ntawm kev tshuaj ntsuam los ntawm 0.5 L kom tau 0.02 moles ib litre. Qhov no yog qhov siab los yog molarity.

Tom qab ntawd, dab tsi yog cov kauj ruam hauv kev daws teeb meem acid puag?

Tsis

1. Yog hais tias koj tsuas muaj ib tug qaug zog acid. Txiav txim siab qhov concentration ntawm cov kua qaub (piv txwv tias tsis muaj dissociation). Saib los yog txiav txim siab K_a.
2. Yog hais tias koj muaj ib tug qaug zog acid thiab lub conjugate puag. Daws rau qhov tsis.
3. Yog tias koj tsuas muaj lub hauv paus conjugate. Kev daws rau pH ntawm lub hauv paus siv K_b thiab qhov sib npaug ntawm hydrolysis.

Cov mis rau titration yog dab tsi?

Siv cov titration mis . Yog hais tias tus titrant thiab analyte muaj 1: 1 mole piv, lub qauv yog molarity (M) ntawm cov kua qaub x ntim (V) ntawm cov kua qaub = molarity (M) ntawm lub hauv paus x ntim (V) ntawm lub hauv paus. (Molarity yog qhov concentration ntawm cov tshuaj hais tawm raws li tus naj npawb ntawm moles ntawm solute ib liter ntawm kev daws.)
