Kutemerwa kweAvailable Chlorine Content muTrichloroisocyanuric Acid neTitration

Zvinhu zvinodiwa uye zvishandiso

1. Soluble starch

2. Yakaiswa sulfuric acid

3. 2000ml Beaker

4. 350ml beaker

5. Mapepa ekuyera uye zviyero zvemagetsi

6. Mvura yakacheneswa

7. Sodium thiosulfate analytical reagent

Kugadzirira stock solution ye sodium thiosulfate

Yera 1000ml mvura yakacheneswa uchishandisa 500ml yekuyeresa makapu kaviri wodira mu2000ml breaker.

Wobva wadira bhodhoro rese re sodium thiosulfate analytical reagent mubeaker zvakananga, Isa beaker pane induction cooker kusvika mushonga wavira kwemaminetsi gumi.

Mushure meizvozvo, Chengetedza ichitonhorera, uye ichiri kwemavhiki maviri, wobva waisefa kuti uwane iyo stock solution ye sodium thiosulfate.

Kugadzirira 1 + 5 sulfuric acid

Yera 750ml mvura yakacheneswa nekushandisa 500ml yekuyeresa kapu kaviri wodira mu1000ml yemumuromo wemusango.

Wobva wayera 150ml concentrated sulfuric acid, Dururirai asidhi mumvura yacheneswa zvishoma nezvishoma, Isai nguva dzose kana muchidira.

Gadzirira 10g/L starch solution

Yera 100ml mvura yakacheneswa nekushandisa 100ml yekuyeresa kapu, Uye woidira mu300ml beaker.

Yera 1g inonyungudika starch mumagetsi chiyero, Uye isa mu50ml beaker.Tora 300ml beaker pane induction cooker kuti mvura ifashaire.

Dururira mvura shoma yakacheneswa kunyungudutsa starch, Wobva wadira starch yakanyungudika mumvura iri kufashaira yakanatswa, Chengetedza ichitonhorera kuti ushandise.

Matanho ekuyera zvirimo zveTrichloroisocyanuric acid

Tora 100ml mvura yakacheneswa Mu 250ml ayodhini flask.

Edza 0.1g TCCA sampuli muchiyero chakanyatsojeka, Ita kuti ive yakarurama kusvika ku 0.001g, Isa muenzaniso wacho zvakananga mu 250ml iodine flask.

Eresa 2g potassium iodide muiodine flask, Uye woisa mu20ml ye20% sulfuric acid, Wobva wasimbisa flask nemvura mushure mekuchenesa mutsipa weflask nekuchenesa bhodhoro.

Ita kuti ive ultrasonic wave Inoinyungudutsa zvachose, Mushure meizvozvo, geza mutsipa webhodhoro uchishandisa mvura yakacheneswa zvakare.

Danho rekupedzisira ndere titrate neyakajairwa titration solution yeSodium thiosulfate, kusvika mhinduro yacho yave muchiedza yeyero isa 2ml starch tracer agent.Uye ramba uchiita titrating kusvika ruvara rwebhuruu rwangonyangarika Ndokubva tapedza.

Rekodha huwandu hweyakadyiwa sodium thiosulfate

Ita kuedza kwakasviba panguva imwe chete
