Kumenya Chloride muri Grade Sodium CMC

Kugena chloride muri sodium yo mu rwego rwa sodium carboxymethyl selulose (CMC) irashobora gukorwa hakoreshejwe uburyo butandukanye bwo gusesengura. Hano, nzagaragaza uburyo bukoreshwa cyane, aribwo buryo bwa Volhard, buzwi kandi nuburyo bwa Mohr. Ubu buryo bukubiyemo titre hamwe na nitrate ya silver (AgNO3) imbere yikimenyetso cya potasiyumu chromate (K2CrO4).

Dore intambwe ku yindi uburyo bwo kumenya chloride muri sodium yo mu rwego rwa ibiryo CMC ukoresheje uburyo bwa Volhard:

Ibikoresho na reagent:

1. Sodium carboxymethyl selulose (CMC) icyitegererezo
2. Ifeza ya nitrate (AgNO3) igisubizo (gisanzwe)
3. Chromate ya Potasiyumu (K2CrO4) igisubizo cyerekana
4. Acide Nitric (HNO3) igisubizo (dilute)
5. Amazi yamenetse
6. 0.1 M Igisubizo cya Sodium chloride (NaCl) igisubizo (igisubizo gisanzwe)

Ibikoresho:

1. Impirimbanyi zisesenguye
2. Amashanyarazi
3. Burette
4. Erlenmeyer flask
5. Imiyoboro
6. Magnetic stirrer
7. metero ya pH (bidashoboka)

Inzira:

1. Gupima neza garama 1 yicyitegererezo cya sodium CMC mumashanyarazi meza kandi yumye 250 mL Erlenmeyer.
2. Ongeramo hafi 100 mL y'amazi yatoboye kuri flask hanyuma ukangure kugeza CMC isheshwe burundu.
3. Ongeramo ibitonyanga bike bya potasiyumu chromate yerekana igisubizo kuri flask. Igisubizo kigomba guhinduka umuhondo ucye.
4. Tanga igisubizo hamwe na nitrate isanzwe ya silver (AgNO3) kugeza igihe imvura itukura-yijimye ya chromate ya silver (Ag2CrO4) igaragara gusa. Iherezo ryerekanwa no gushiraho imvura itukura-yijimye.
5. Andika ingano ya AgNO3 igisubizo gikoreshwa muri titre.
6. Ongera usubiremo titre hamwe nibindi byitegererezo byumuti wa CMC kugeza ibisubizo bihuye bibonetse (urugero, ingano ya titre).
7. Tegura icyemezo cyuzuye ukoresheje amazi yatoboye aho gukoresha icyitegererezo cya CMC kugirango ubaze chloride iyo ari yo yose igaragara muri reagent cyangwa ibirahure.
8. Kubara ibiri muri chloride muri sample ya sodium ya CMC ukoresheje formula ikurikira:

Aho:

• $�$

  V = ingano ya AgNO3 igisubizo gikoreshwa muri titre (muri mL)

• $�$

  N = ibisanzwe bya AgNO3 igisubizo (muri mol / L)

• $�$

  M = ububobere bwa NaCl igisubizo gisanzwe (muri mol / L)

• $�$

  W = uburemere bwa sodium ya sample ya CMC (muri g)

Icyitonderwa: Ikintu
$35.45$

35.45 ikoreshwa muguhindura chloride kuva kuri garama kugeza kuri garama ya ion ya chloride (
$��-$

Cl−).

Icyitonderwa:

1. Koresha imiti yose witonze kandi wambare ibikoresho bikingira umuntu.
2. Menya neza ko ibirahuri byose bifite isuku kandi byumye kugirango wirinde kwanduza.
3. Suzuma igisubizo cya nitrate ya silver ukoresheje urwego rwibanze nka sodium chloride (NaCl).
4. Kora titre buhoro buhoro hafi yanyuma kugirango umenye ibisubizo nyabyo.
5. Koresha magnetiki stirrer kugirango umenye neza kuvanga ibisubizo mugihe cya titre.
6. Subiramo titre kugirango umenye neza ibisubizo neza.

Ukurikije ubu buryo, urashobora kumenya chloride iri mu biribwa byo mu rwego rwa sodium carboxymethyl selulose (CMC) mu buryo bwuzuye kandi bwizewe, ukemeza ko hubahirizwa ibipimo ngenderwaho hamwe n’ibisabwa kugira ngo hongerwe ibiryo.
