Mkpebi nke Chloride na nri ọkwa sodium CMC

Enwere ike ime mkpebi nke chloride na ọkwa nri sodium carboxymethyl cellulose (CMC) site na iji ụzọ nyocha dị iche iche. N'ebe a, m ga-akọwapụta usoro a na-ejikarị eme ihe, nke bụ usoro Volhard, nke a makwaara dị ka usoro Mohr. Usoro a gụnyere titration na silver nitrate (AgNO3) ngwọta na ọnụnọ nke potassium chromate (K2CrO4) egosi.

Nke a bụ usoro nzọụkwụ site na mkpebi siri ike nke chloride na ọkwa nri sodium CMC site na iji usoro Volhard:

Akụrụngwa na Reagents:

1. Sodium carboxymethyl cellulose (CMC) sample
2. Silver nitrate (AgNO3) ngwọta (ọkọlọtọ)
3. Potassium chromate (K2CrO4) ngwọta egosi
4. Nitric acid (HNO3) ngwọta (tugharia)
5. Mmiri distilled
6. 0.1M Sodium chloride (NaCl) ngwọta (ọkọlọtọ ngwọta)

Akụrụngwa:

1. Ntụle nyocha
2. Mpempe ụda olu
3. Burette
4. Erlenmeyer flask
5. Pipettes
6. Magnetị mkpagharị
7. mita pH (nhọrọ)

Usoro:

1. Tụru nke ọma ihe dị ka gram 1 nke ihe nlele sodium CMC n'ime flask Erlenmeyer 250 ml dị ọcha ma kpọọ nkụ.
2. Tinye ihe dị ka 100 ml nke mmiri a na-ekpo ọkụ na flask ma kpalie ruo mgbe CMC gbazere kpamkpam.
3. Tinye ntakịrị ihe ngwọta potassium chromate n'ime ite ahụ. Ihe ngwọta kwesịrị ịtụgharị odo odo.
4. Titrate ihe ngwọta na ngwọta ọlaọcha nitrate ọkọlọtọ (AgNO3) ruo mgbe chromate ọlaọcha na-acha ọbara ọbara-agba aja aja (Ag2CrO4) pụtara. A na-egosi njedebe njedebe site na nguzobe nke na-adịgide adịgide na-acha uhie uhie-agba aja aja.
5. Dekọọ olu nke ngwọta AgNO3 ejiri maka titration.
6. Tinyegharịa titration ahụ yana nleba anya nke ngwọta CMC ruo mgbe enwetara nsonaazụ nkwekọrịta (ya bụ, mpịakọta titration na-agbanwe agbanwe).
7. Kwadebe mkpebi efu site na iji mmiri distilled kama iji nlele CMC iji nweta chloride ọ bụla dị na reagents ma ọ bụ glassware.
8. Gbakọọ ọdịnaya chloride na nlele sodium CMC site na iji usoro a:

Ebe:

• $�$

  V = olu nke ngwọta AgNO3 ejiri maka titration (na mL)

• $�$

  N = nkịtị nke ngwọta AgNO3 (na mol / L)

• $�$

  M = molarity nke NaCl ọkọlọtọ ngwọta (na mol/L)

• $�$

  W = arọ nke ihe nlele sodium CMC (na g)

Mara: Ihe kpatara ya
$35.45$

A na-eji 35.45 gbanwee ọdịnaya chloride site na gram gaa na gram nke ion chloride (
$��-$

Cl-).

Mkpachapụ anya:

1. Jiri nlezianya jikwaa kemịkalụ niile ma yikwasị akụrụngwa nchedo onwe gị kwesịrị ekwesị.
2. Gbaa mbọ hụ na ngwongwo iko niile dị ọcha ma kpọọ nkụ ka ịzenarị mmetọ.
3. Hazie ngwọta nitrate ọlaọcha site na iji ọkọlọtọ bụ isi dị ka ngwọta sodium chloride (NaCl).
4. Mee titration ahụ nwayọ n'akụkụ ebe njedebe iji hụ na nsonaazụ ziri ezi.
5. Jiri magnetik mkpagharị iji hụ na agwakọta ihe ngwọta nke ọma n'oge titration.
6. Tinyegharịa titration ahụ iji hụ na izi ezi na izi ezi nke nsonaazụ ya.

Site n'ịgbaso usoro a, ị nwere ike ikpebi ọdịnaya chloride dị na ọkwa nri sodium carboxymethyl cellulose (CMC) n'ụzọ ziri ezi na ntụkwasị obi, na-ahụ na nnabata na ụkpụrụ ịdị mma yana ihe iwu chọrọ maka mgbakwunye nri.
