Ho fumana hore na Chlorine e fumaneha ka har'a Trichloroisocyanuric Acid ka Titration ke bokae

Lisebelisoa le lisebelisoa tse hlokahalang

1. Setache se qhibilihang

2. Asiti e tiileng ea sulfuric

3. Beaker ea 2000ml

4. Beaker ea 350ml

5. Pampiri ea ho lekanya le sekala sa elektroniki

6. Metsi a hloekisitsoeng

7. Reagent ea tlhahlobo ea sodium thiosulfate

Ho lokisa tharollo ea sodium thiosulfate

Lekanya metsi a hloekisitsoeng a 1000ml ka ho sebelisa likopi tsa ho lekanya tsa 500ml habeli ebe u a tšela ka har'a sesebelisoa sa ho qhaqha sa 2000ml.

Ebe o tšela botlolo yohle ya sodium thiosulfate analytical reagent ka hara beaker ka ho toba, Beha beaker hodima beaker ya induction ho fihlela tharollo e bela metsotso e leshome.

Kamora moo, e boloke e pholile, 'me e sa sisinyehe libeke tse peli, ebe u e sefa ho fumana tharollo ea sodium thiosulfate.

Ho lokisa 1+5 sulfuric acid

Lekanya metsi a hloekisitsoeng a 750ml ka ho sebelisa kopi ea ho lekanya ea 500ml habeli ebe u e tšela ka botlolong ea 1000ml ea wild-mouth.

Ebe o lekanya 150ml ea sulfuric acid e matlafetseng, Tšela asiti ka metsing a hloekisitsoeng butle, E hlohlelle nako le nako ha u e tšela.

Lokisetsa tharollo ea starch ea 10g/L

Lekanya metsi a hloekisitsoeng a 100ml ka ho sebelisa kopi ea ho lekanya ea 100ml, 'me u e tšele ka har'a beaker ea 300ml.

Lekanya 1g ea starch e qhibilihang ka sekala sa elektroniki, 'me u e kenye ka har'a beaker ea 50ml. Nka beaker ea 300ml ka setofong sa induction ho etsa hore metsi a bele.

Tšela metsi a manyane a hloekisitsoeng ho qhala starch, Ebe o tšela starch e qhibilihisitsoeng metsing a belang a hloekisitsoeng, E boloke e pholile bakeng sa tšebeliso.

Mehato ea ho lekanya litaba tsa Trichloroisocyanuric acid

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

Lekanya sampole ea TCCA ea 0.1g ka sekala se nepahetseng, Etsa hore e nepahale ho fihlela ho 0.001g, Beha sampole ka ho toba ka har'a flask ea iodine ea 250ml.

Lekanya 2g ea potassium iodide ka har'a flask ea iodine, 'me u e tšele ka har'a 20ml ea 20% ea sulfuric acid, ebe u koala flask ka metsi ka mor'a ho hloekisa molala oa flask ka ho hloekisa botlolo.

E etse leqhubu la ultrasonic le e qhibilihisang ka ho feletseng, Kamora moo, hlwekisa 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 mosehla o bobebe beha 2ml starch tracer agent. 'Me u tsoele pele ho titrate ho fihlela 'mala o moputsoa o nyamela feela. Ebe re ka e qeta.

Ngola bophahamo ba sodium thiosulfate e jeoang

Etsa teko e ntšo ka nako e le 'ngoe

Mokhoa oa ho bala liphetho tsa tlhahlobo
