Kudziwa Kuchuluka kwa Chlorine komwe kulipo mu Trichloroisocyanuric Acid pogwiritsa ntchito Titration

Zipangizo ndi zida zofunika

1. Wowuma wosungunuka

2. Sulfuric acid yokhazikika

3. 2000ml Beaker

4. 350ml beaker

5. Mapepala oyezera ndi masikelo apakompyuta

6. Madzi oyera

7. Sodium thiosulfate analytical reagent

Kukonzekera njira yothetsera sodium thiosulfate

Yesani madzi oyera okwana 1000ml pogwiritsa ntchito makapu oyezera a 500ml kawiri ndikutsanulira mu breaker ya 2000ml.

Kenako tsanulirani botolo lonse la sodium thiosulfate analytical reagent mu beaker mwachindunji, Ikani beaker pa induction cooker mpaka yankho litawira kwa mphindi khumi.

Pambuyo pake, sungani pamalo ozizira, ndipo musamavutike kwa milungu iwiri, kenako sefani kuti mupeze yankho la sodium thiosulfate.

Kukonzekera 1+5 sulfuric acid

Yesani madzi oyera okwana 750ml pogwiritsa ntchito chikho choyezera cha 500ml kawiri ndikutsanulira mu botolo la 1000ml la wild-mouth.

Kenako yezani 150ml ya asidi wokhuthala wa sulfuric, Thirani asidiyo m'madzi oyera pang'onopang'ono, Sakanizani nthawi zonse mukamathira.

Konzani 10g/L starch solution

Yesani madzi oyera 100ml pogwiritsa ntchito chikho choyezera cha 100ml, ndipo muwathire mu 300ml ya beaker.

Yesani 1g ya sitachi yosungunuka mu sikelo yamagetsi, Ndipo ikani mu 50ml ya beaker. Tengani 300ml ya beaker pa induction cooker kuti madzi awirire.

Thirani madzi pang'ono oyeretsedwa kuti musungunule sitachi, Kenako tsanulirani sitachi yosungunuka m'madzi otentha oyeretsedwa, Sungani ozizira kuti mugwiritse ntchito.

Njira zoyezera kuchuluka kwa Trichloroisocyanuric acid

Imwani madzi oyeretsedwa 100ml mu botolo la ayodini la 250ml.

Yesani chitsanzo cha TCCA cha 0.1g mu sikelo yolondola, Pangani kuti chikhale cholondola mpaka 0.001g, Ikani chitsanzocho mwachindunji mu botolo la ayodini la 250ml.

Yesani 2g ya potaziyamu iodide mu botolo la ayodini, Ndipo ikaninso mu 20ml ya 20% sulfuric acid, Kenako tsekani botolo ndi madzi mutatsuka botololo poyeretsa botololo.

Pangani kukhala mafunde a ultrasonic omwe amasungunula kwathunthu, Pambuyo pake, yeretsani botolo pogwiritsa ntchito madzi oyera kachiwiri.

Gawo lomaliza ndikuyika titrate ndi yankho la titration la Sodium thiosulfate, mpaka yankholo likhale lachikasu chopepuka, ikani 2ml ya starch tracer agent. Ndipo pitirizani kuyika titrate mpaka mtundu wabuluu utasowa. Kenako tikhoza kumaliza.

Lembani kuchuluka kwa sodium thiosulfate yomwe mwamwa

Yesani kuyesa kwakuda nthawi yomweyo

Kuwerengera njira yopezera zotsatira za mayeso
