Kuongororwa kweChlorine Inowanikwa muTrichloroisocyanuric Acid neTitration

Zvinhu zvinodiwa uye maturusi

1. Sitachi inonyunguduka

2. Asidhi yesulfuric yakakora

3. Bheki re2000ml

4. Bheki re350ml

5. Mapepa ekuyera uye zviyero zvemagetsi

6. Mvura yakachena

7. Sodium thiosulfate analytical reagent

Kugadzirira mhinduro ye sodium thiosulfate

Yera 1000ml yemvura yakacheneswa uchishandisa makapu ekuyera 500ml kaviri woidururira mumudziyo we2000ml.

Wobva wadurura bhodhoro rese re sodium thiosulfate analytical reagent mubeaker zvakananga, Isa beaker pa induction cooker kusvika mvura yafashaira kwemaminitsi gumi.

Mushure meizvozvo, chengetai ichitonhorera, uye igare kwemavhiki maviri, mozoisefa kuti muwane sodium thiosulfate.

Kugadzirira 1+5 sulfuric acid

Yera 750ml yemvura yakachena uchishandisa kapu yekuyera 500ml kaviri woidururira mubhodhoro re1000ml remumuromo wemusango.

Wobva wayera 150ml concentrated sulfuric acid, Dururira acid mumvura yakacheneswa zvishoma nezvishoma, Kurunga nguva dzese paunenge uchidurura.

Gadzirira 10g/L starch solution

Yera 100ml yemvura yakachena uchishandisa kapu yekuyera 100ml, Woidururira mu 300ml yewaini.

Yera 1g yestarch inonyungudika mu electronic scale, Woiisa mu 50ml ye dhishi. Tora 300ml ye dhishi iri mu induction cooker kuti mvura ifashaire.

Dururirai mvura diki yakacheneswa kuti munyungudise sitachi, Wobva wadira sitachi yakanyungudutswa mumvura iri kufashaira, Chengetai ichitonhorera kuti mushandise.

Matanho ekuyera huwandu hweTrichloroisocyanuric acid

Tora 100ml yemvura yakachena mu 250ml ye bhodhoro re iodine.

Yera 0.1g TCCA sampuro muchiyero chakarurama, Ita kuti ive chaiyo kusvika 0.001g, Isa sampuro zvakananga mu 250ml ye iodine flask.

Yera 2g yepotassium iodide mubhodhoro reayodini, Wobva waisawo mu20ml ye20% sulfuric acid, wobva wavhara bhodhoro nemvura mushure mekuchenesa mutsipa webhodhoro nekuchenesa bhodhoro.

Gadzirai mu ultrasonic wave. Izvi zvinoinyungudutsa zvachose. Mushure meizvozvo, chenesai muromo webhodhoro nemvura yakacheneswa zvakare.

Danho rekupedzisira nderekuti titrate neSodium thiosulfate, kusvika mhinduro yava yero yakajeka, isa 2ml starch tracer agent. Uye ramba uchiti titrate kusvika ruvara rwebhuruu rwanyangarika. Zvadaro tinogona kuipedza.

Nyora huwandu hwe sodium thiosulfate inonwiwa

Ita kuyedza kwenhema panguva imwe chete

Kuverenga maitiro emhedzisiro yekuyedza
