2. Hydroxide
3. Igisubizo cyerekana Ponolphthalein
4. Sodium Bicarbonate
5. Acide sulfuric
6. Potasiyumu iyode
7. Sodium Thiosulfate Igisubizo cyigitekerezo (0.02MOL / L)
8. Igisubizo cya Strarte
ibikoresho:
Imyiteguro yicyitegererezo:
1. Sodium hydroxide igisubizo (0.02Mol / l)
Kwitegura: Fata 5.6Ml yububiko bwa sodium yubusa, ongeraho amazi akonje kugirango ayikore 1000ml.
Calibration: Fata hafi 6G ya 6G ya hydrogen ya potasipi yumye kuri 105 ° C kugeza uburemere buriho, ongeraho 50m wamazi akonje yatetse, ahinda umushyitsi bishoboka; Ongeramo ibitonyanga 2 byerekana igisubizo cya fenolphthalein, koresha iyi titrasiyo yamazi, mugihe wegereye ingingo zanyuma, PASISSIM Hydrogen Phthalate igomba gushonga rwose, kandi yamagana kugeza igisubizo kiba umutuku. Buri 1ml ya sodium hydroxide igisubizo (1mol / l) bihwanye na 20.42mg ya potasiyumu hydrogen phthalate. Kubara kwibanda kuri iki gisubizo gishingiye kubijyanye no gukoresha iki gisubizo hamwe numubare wa potasinim hydrogen phthalate yafashwe. Firetitive dilute inshuro 5 kugirango ukore kwibanda 0.02MOL / L.
Ububiko: Shyira muri polyethylene icupa rya plastiki kandi uyishyireho kashe; Hano hari umwobo 2 mucomeka, kandi umuyoboro 1 winjijwe muri buri mwobo, umuyoboro wa 1 uhuza na soda umuyoboro wa soda, na tube 1 ukoreshwa mu konsa amazi.
2. Igitekerezo cya Phenolphthalein Fata 1G ya Phenolphthalein, ongeramo 100ml ya ethanol kugirango ishonge
3. Sodium Thiosulfate Igisubizo cyigitekerezo (0.02MOL / L): Fata 26G ya Sodium Thiosulfate, SHAKA AKARERE KA ANTHSMS HOMYSM, SHAKA Ukwezi Akayunguruzo. Calibration: Fata hafi 0.15g ya potasiyumu isanzwe yumye kuri 120 ° C hamwe nuburemere buhoraho, shyira mu icupa rya mudes, ongeraho amacupa ya kera, ongeraho PATAsisiyumu, Shake witonze kugirango ushishoze, ongeraho 40ml ya acide sulfuric, ihindagurika neza kandi ikimenyetso; Nyuma yiminota 10 ahantu hijimye, ongeraho 250ml y'amazi kugirango ugabanye umwanya wanyuma, ongeraho 3ml yo gukemura ibipimo byanyuma, komeza amazina yumuti kugeza igihe ibara ryubururu ribuze kandi ryigice ikoreshwa nkibigeragezo bidahwitse. Buri 1ml ya sodium thuosulfate (0.1MOL / L) ihwanye na 4.903g ya potasiyumu diichromate. Kubara kwibanda kubisubizo ukurikije uko igisubizo hamwe numubare wa potasimu wafashwe. Firetitive dilute inshuro 5 kugirango ukore kwibanda 0.02MOL / L. Niba ubushyuhe bwo mucyumba kiri hejuru ya 25 ° C, ubushyuhe bwikibazo cyo gukemura hamwe namazi yo kwikuramo agomba gukonjeshwa kugeza kuri 20 ° C.
4. Igisubizo cya Starch Gufata 0.5G cyibisambo byoroheje, ongeraho 5ml y'amazi hanyuma utekereze cyane, utekereze buhoro, utekereze cyane, ureke gukonjesha, usuke umugozi, Kandi iriteguye.
Iki gisubizo kigomba gutegurwa vuba mbere yo gukoresha.
INTAMBWE: Fata 0.1G k'iki gicuruzwa, upima neza, shyira mu icupa rya none d, ongeramo 10ml ya 30% (G / G) Chichmide. Uzuza imiyoboro ibyara b hamwe namazi kumutwe, hanyuma uhuze ishami ryinzira. Kwibiza byombi Umugezi wa azote utemba kandi ugenzure igipimo cyacyo kugeza 1 kubyimba kumasegonda. Mu minota 30, uzamure ubushyuhe bwo kwiyuhagira kuri 155ºc, hanyuma ukomeze ubushyuhe kugeza kuri ml 50 yo kuringaniza bivuye mu nkingi, kwoza amazi, ongeraho ku muti wakusanyirijwe, ongeramo 3 ibitonyanga by'igisubizo cyerekana ibimenyetso bya Pheolphthalein, kandi titra agaciro ka PH ni 6.9-7.1 (yapimye metero ya acide Kugeza igihe ntakindi dioxyde de carbone, ongeraho 1.0g ya potasiyumu, hanyuma uhaguruke neza, ongeraho 1ML wijimye. Iherezo ryanyuma, andika umubare wafashwe v2 (ml). Mu kindi kizamini cyubusa, andika umubumbe VA na vb (ml) ya sodium ya sodium yakoreshejwe. 0.02Mol / L) na sodium thiosulfate igisubizo (0.02MOL / L).
