Mkpebi ọdịnaya Chlorine dị na Trichloroisocyanuric Acid site na Titration

Ihe na ngwaọrụ achọrọ

1. starch soluble

2. Sulfuric acid gbadoro ụkwụ

3. 2000ml Beaker

4. 350ml ntụ ọka

5. Ịtụ akwụkwọ na eletrọnịkị akpịrịkpa

6. Mmiri dị ọcha

7. Sodium thiosulfate analytical reagent

Na-akwadebe ihe ngwọta nke sodium thiosulfate

Tụọ 1000ml mmiri dị ọcha site na iji iko nha 500ml ugboro abụọ ma wunye ya n'ime mpempe 2000ml.

Mgbe ahụ, wunye otu karama sodium thiosulfate analytical reagent n'ime beaker ozugbo, tinye beaker na osi nri induction ruo mgbe ihe ngwọta na-esi esi nkeji iri.

Mgbe nke ahụ gasịrị, mee ka ọ dị jụụ, ma ka dị izu abụọ, wee nyochaa ya iji nweta ngwọta ngwaahịa nke sodium thiosulfate.

Na-akwado 1 + 5 sulfuric acid

Tụọ mmiri 750ml dị ọcha site na iji iko nha 500ml ugboro abụọ ma wunye ya na karama ọnụ ọhịa 1000ml.

Mgbe ahụ tụọ 150ml concentrated sulfuric acid, Wunye acid n'ime mmiri dị ọcha nwayọọ nwayọọ, kpalie ya mgbe niile mgbe ị na-awụsa.

Kwadebe 10g / L starch ngwọta

Tua 100ml mmiri dị ọcha site na iji iko nha 100ml, wee wunye ya na beaker 300ml.

tụọ 1g soluble starch na eletrọnịkị ọnụ ọgụgụ, ma tinye ya n'ime 50ml beaker.Were 300ml beaker na osi nri induction iji mee ka mmiri sie.

Yet obere ọcha mmiri igbari na starch, Mgbe ahụ, wụsa etisasịwo starch n'ime esi ọcha mmiri, na-ọ dị jụụ maka ojiji.

Nzọụkwụ maka ịlele ọdịnaya nke Trichloroisocyanuric acid

Were 100ml mmiri dị ọcha n'ime 250ml iodine flask.

Tụlee ihe atụ 0.1g TCCA n'ogo ziri ezi, mee ka ọ bụrụ 0.001g ziri ezi, tinye ihe nlele ahụ ozugbo n'ime flask iodine 250ml.

Tụọ 2g potassium iodide n'ime flask ayodiin, ma tinyekwa n'ime 20ml nke 20% sulfuric acid, wee mechie flask ahụ na mmiri ka ihichapụ olu flask site na ihicha karama.

Mee ya n'ime ultrasonic ebili mmiri nke na-agbaze ya kpamkpam, Mgbe nke ahụ gasịrị, hichaa olu karama site na iji mmiri dị ọcha ọzọ.

Nzọụkwụ ikpeazụ bụ titrate na ọkọlọtọ titration ngwọta nke Sodium thiosulfate, ruo mgbe ngwọta bụ ìhè odo agba tinye 2ml starch tracer agent.Na na-na-titrating ruo na-acha anụnụ anụnụ na agba na-apụ n'anya Mgbe ahụ anyị nwere ike mechaa ya.
