Ka Ho'oholo 'ana i ka ma'i'o Chlorine i loa'a i loko o ka Acid Trichloroisocyanuric ma ka Titration

Pono nā mea hana a me nā mea hana

1. Mākaʻi hoʻoheheʻe

2. Aakika sulfuric concentrated

3. 2000ml Beaker

4. 350ml ka ipuhao

5. Pepa kaumaha a me nā unahi uila

6. Ka wai hoomaemae

7. Sodium thiosulfate analytical reagent

Ka hoʻomākaukau ʻana i ka hoʻonā waiwai o ka sodium thiosulfate

E ana i 1000ml wai i hoʻomaʻemaʻe ʻia me ka hoʻohana ʻana i nā kīʻaha ana 500ml ʻelua a ninini ʻia i loko o kahi mea wāwahi 2000ml.

A laila, ninini i ka ʻōmole holoʻokoʻa o ka sodium thiosulfate analytical reagent i loko o ka beaker pololei, E kau i ka beaker ma luna o ka mea kuke induction a hiki i ka paila ʻana o ka hopena no ʻumi mau minuke.

Ma hope o kēlā, e hoʻomau i ka maʻalili, a hoʻomau no ʻelua pule, a laila kānana iā ia e loaʻa ai ka hopena waiwai o ka sodium thiosulfate.

E hoʻomākaukau ana i ka sulfuric acid 1+5

E ana i 750ml wai i hoʻomaʻemaʻe ʻia me ka hoʻohana ʻana i ke kīʻaha ana 500ml ʻelua a ninini i loko o ka ʻōmole waha hihiu 1000ml.

A laila e ana i ka 150ml sulfuric acid concentrated, E ninini i ka waika i loko o ka wai hoʻomaʻemaʻe mālie, E hoʻoulu i nā manawa a pau i ka ninini ʻana.

E hoʻomākaukau i ka hopena starch 10g/L

E ana i 100ml wai i hoʻomaʻemaʻe ʻia me ka hoʻohana ʻana i 100ml ana kīʻaha, A ninini i loko o 300ml beaker.

E ana i 1g soluble starch ma ka unahi uila, A e hookomo i loko o ka bea 50ml.E lawe i ka beaker 300ml ma ka ipu kuke e hoʻolapalapa ai i ka wai.

E ninini i ka wai hoʻomaʻemaʻe liʻiliʻi e hoʻoheheʻe i ka starch, A laila e ninini i ka starch i hoʻoheheʻe ʻia i loko o ka wai hoʻomaʻemaʻe e paila ana, E mālama i ka maʻa no ka hoʻohana ʻana.

Nā ʻanuʻu no ke ana ʻana i ka ʻiʻo Trichloroisocyanuric acid

E lawe i 100ml wai maʻemaʻe i loko o 250ml iodine hue.

E ana i 0.1g TCCA hāpana ma ka precision unahiʻole, E hana pololei i 0.001g, E kau i ka hāpana i loko o 250ml iodine ipu.

E ana i ka 2g potassium iodide i loko o ka ipu iodine, A e hoʻokomo pū i loko o 20ml o 20% sulfuric acid, A laila e hoʻopaʻa i ka ipu i ka wai ma hope o ka hoʻomaʻemaʻe ʻana i ka ʻāʻī o ka hue ma ka hoʻomaʻemaʻe ʻana i ka hue.

E hana i loko o ka hawewe kani ultrasonic E hoʻoheheʻe loa ia, Ma hope o kēlā, e hoʻomaʻemaʻe i ka ʻāʻī o ka ʻōmole me ka wai maʻemaʻe hou.

ʻO ka ʻanuʻu hope, ʻo ia ka titrate me ka solution titration maʻamau o Sodium thiosulfate, a hiki i ka waiho ʻana i ka waihoʻoluʻu melemele māmā e hoʻokomo i 2ml starch tracer agent.A hoʻomau i ka titrating a hiki i ka nalo ʻana o ke kala uliuli A laila hiki iā mākou ke hoʻopau.

E hoʻopaʻa i ka nui o ka sodium thiosulfate i hoʻopau ʻia

Hana i kahi hoʻokolohua ʻeleʻele i ka manawa like

Ke helu ʻana i nā hopena hoʻokolohua
