Boikemisetso ba Lintho tse Fumanehang tsa Chlorine ho Trichloroisocyanuric Acid ka Titration

Lisebelisoa le lisebelisoa tse hlokahalang

1. starch e qhibilihang

2. E tsitsitse sulfuric acid

3. 2000ml Beaker

4. 350ml beaker

5. Lipampiri tse bekhang le likala tsa elektronike

6. Metsi a hloekisitsoeng

7. Sodium thiosulfate analytical reagent

Ho lokisa tharollo ea stock ea sodium thiosulfate

Lekanya 1000ml ea metsi a hloekisitsoeng ka ho sebelisa 500ml ea ho lekanya linoelo habeli 'me u a tšele ka har'a sekheo sa 2000ml.

Ebe u tšela botlolo eohle ea sodium thiosulfate analytical reagent ka beakeng ka kotloloho, Beha beake holim'a seapehi sa induction ho fihlela tharollo e bela metsotso e leshome.

Ka mor'a moo, e boloke e pholile, 'me e ntse e le libeke tse peli, ebe u e sefa ho fumana tharollo ea sodium thiosulfate.

Ho lokisetsa 1+5 sulfuric acid

Lekanya metsi a hloekisitsoeng a 750ml ka ho sebelisa kopi ea ho lekanya ea 500ml habeli ebe o e tšela ka botlolong ea molomo oa naha ea 1000ml.

Ebe u lekanya 150ml concentrated sulfuric acid, Tšela asiti ka metsing a hloekisitsoeng butle-butle, E hlohlelletse ka linako tsohle ha u tšela.

Lokisetsa tharollo ea 10g/L ea starch

Lekanya 100ml ea metsi a hloekisitsoeng ka ho sebelisa kopi ea ho lekanya ea 100ml, 'me ue tšele ka bekeng ea 300ml.

Lekanya setache se qhibilihang ka 1g ka sekala sa elektroniki, 'me u se kenye ka bekeng ea 50ml. Nka beaker ea 300ml holim'a cooker ea induction ho etsa hore metsi a belise.

Tšela metsi a hloekisitsoeng ho qhala starch, ebe u tšela starch e qhibilihisitsoeng ka metsing a belang a hloekisitsoeng, 'Me e boloke e pholile hore e sebelisoe.

Mehato ea ho lekanya litaba tsa Trichloroisocyanuric acid

Tšela 100ml ea metsi a hloekisitsoeng ka har'a botlolo ea iodine ea 250ml.

Lekanya sampole ea 0.1g TCCA ka tekanyo e nepahetseng, Etsa hore e nepahale ho 0.001g, Beha sampole ka kotloloho ka har'a botlolo ea iodine ea 250ml.

Lekanya 2g iodide ea potasiamo ka har'a botlolo ea iodine, 'me hape u kenye ka 20ml ea 20% sulfuric acid, Ebe u tiisa botlolo ka metsi ka mor'a ho hloekisa molala ka ho hloekisa botlolo.

E etsa hore e be ultrasonic wave E qhibilihang ka ho feletseng, Ka mor'a moo, hloekisa molala oa botlolo u sebelisa metsi a hloekisitsoeng hape.

Mohato oa ho qetela ke ho titrate ka tharollo e tloaelehileng ea titration ea sodium thiosulfate, ho fihlela tharollo e le 'mala o mosehla o khanyang beha 2ml starch tracer agent. 'Me u 'ne u titrating ho fihlela' mala o moputsoa o nyamela Joale re ka o qeta.

Rekota bophahamo ba sodium thiosulfate e sebelisitsoeng
