Awọn igbesẹ fun wiwọn akoonu ti Trichloroisocyanuric acid

Mu 100ml omi ti a sọ di mimọ sinu igo iodine 250ml.

Ṣe iwọn 0.1g TCCA ayẹwo ni iwọn konge, Ṣe deede si 0.001g, Fi ayẹwo naa taara sinu ọpọn iodine 250ml.

Ṣe iwọn 2g potasiomu iodide sinu iyẹfun iodine, Ati tun fi sinu 20ml ti 20% sulfuric acid, Lẹhinna fi omi ṣan omi lẹhin fifọ ọrùn flask nipasẹ fifọ igo.

Ṣe o sinu igbi ultrasonic Eyi ti o tu patapata, Lẹhin eyi, nu ọrun igo naa pẹlu lilo omi mimọ lẹẹkansi.

Igbesẹ ti o kẹhin ni lati titrate pẹlu ojutu titration boṣewa ti iṣuu soda thiosulfate, titi ti ojutu naa yoo wa ni awọ ofeefee ina fi oluranlowo sitashi 2ml. Ati ki o tẹsiwaju titrating titi awọ buluu yoo kan parẹ Lẹhinna a le pari rẹ.

Ṣe igbasilẹ iwọn didun iṣuu soda thiosulfate ti o jẹ
