Dhibaatada Titration Xalka Tallaabo-tallaabo ah

  1. Tallaabada 1: Go'aami [OH-] Bar kasta oo NaOH ah waxay yeelan doontaa hal bar oo OH ah-.
  2. Tallaabada 2: Go'aami tirada moles ee OH- Molarity = tirada moles/mugga.
  3. Tallaabada 3: Go'aami tirada moles ee H+
  4. Tallaabada 4: Go'aami diiradda HCl.

Sidoo kale waxaa la is weydiin karaa, sidee loo xisaabiyaa titration?

Isticmaalka titration formula. Haddii titrant iyo analyte ay leeyihiin saamiga 1:1 mole, qaacidadu waa molarity (M) ee aashitada x mugga (V) ee acid = molarity (M) ee saldhigga x mugga (V) ee saldhigga. (Molarity waa uruurinta xalka lagu muujiyey sida tirada moles of solute halkii litir oo xal ah.)

Xagga sare, waa maxay dareenka NaOH? Tusaale ahaan, 0.25 M NaOH Xalka (kan waxaa loo akhriyaa sida 0.25 molar) wuxuu ka kooban yahay 0.25 moles oo ah sodium hydroxide litir kasta oo xal ah. Mar kasta oo aad aragto soo gaabinta M waa inaad isla markiiba uga fikirtaa mol/L.

Halkan, sidee ayaad ku heli kartaa uruurinta HCl ee titration with NaOH?

Xisaabi fiirsashada hydrochloric acid

  1. Mugga xalalka sodium hydroxide = 25.00 ÷ 1000 = 0.0250 dm 3
  2. Qadarka sodium hydroxide = 0.200 × 0.0250 = 0.005 mol.
  3. Marka la eego isla'egta, 0.005 mol ee NaOH waxa uu kaga falceliyaa 0.005 mol ee HCl.
  4. Mugga hydrochloric acid = 22.70 ÷ 1000 = 0.0227 dm 3

Waa maxay tilmaame ku jira titration?

Tilmaame: Waa walax beddesha midabka iyadoo ka jawaabaysa isbeddel kiimikaad. Acid-saldhig Tilmaame (tusaale ahaan, phenolphthalein) midab beddela iyadoo ku xidhan pH-ga. Dib u habeyn tilmaamayaasha sidoo kale loo isticmaalo. Dhibic ka mid ah Tilmaame xal ayaa lagu daraa titration bilowga; meesha ugu dambaysa ayaa la gaadhay marka midabku is beddelo.
