5. Liteko:
1. Asiti e Foreimi:
a. Mokhoa: Bekha hoo e ka bang 5 g ea sampole (u sebelisa tekanyo ea tekheniki) ka beaker ea 100 ml. Kenya marotholi a 2 a tharollo ea phenolphthalein indicator 'me u e fetole ka tharollo ea 2 N NaOH ho fihlela ho hlaha 'mala o mofubelu. E fetole ka bateng ea metsi ho fihlela halofo ea molumo oa pele. E pholise, e behe asiti ka 5 ml ea HCl e matlafalitsoeng, 'me u e fetisetse ka bongata ka har'a flask ea iodine ea 250 ml e nang le 50 ml ea metsi le 50 ml ea tharollo ea 0.1 N NaBrO. E thibelle ka thata, e kopanye hantle, 'me u e lumelle hore e eme metsotso e 30. Kenya 15 ml ea tharollo ea 16.5% KI, 20 ml ea 6 N HCl, le 2 ml ea tharollo ea starch indicator. E tšele ka tharollo ea 0.1 N Na₂S₂O₃ ho fihlela 'mala o moputsoa o nyamela (qetellong). Etsa teko e se nang letho ka nako e le 'ngoe.
b. Palo: (Sekheo sa ml – Sampole ea ml) × 0.1 (Tloaelo) × 0.02301 = ligrama tsa HCOOH
c. Sehlopha sa Glacial Acetic Tlhokomeliso: Ho futhumatsa ka bateng ea metsi kamora ho eketsa NaOH ho reretsoe ho mouoane le ho tlosa acetaldehyde, e leng se neng se tla baka liphetho tse phahameng. Sehlopha sa Glacial Acetic.
2. Acetaldehyde:
a. Mokhoa: Bekha hoo e ka bang 10 g ea glacial acetic acid (u sebelisa tekanyo ea tekheniki) ka har'a flask ea iodine ea 250 ml. Kenya 50 ml ea metsi, ebe u tšela 10 ml ea tharollo ea 4% NaHSO₃ ka har'a flask. E thibe ka thata, e sisinye, 'me u e lumelle hore e eme metsotso e 30. Kenya 2 ml ea tharollo ea starch indicator 'me u e titre ka tharollo ea 0.1 N Iodine ho fihlela 'mala o moputsoa o hlaha (qetellong). Etsa teko e se nang letho ka nako e le 'ngoe.
b. Palo: (Sekheo sa ml – Sampole ya ml) × 0.1 (Tloaelo) × 0.02203 = digrama tsa CH₃CHO
6. Tokisetso ea Reagent:
Tharollo ea 0.1 N Sodium Hypobromite (NaBrO): Kenya 2.8 ml ea bromine ho 500 ml ea metsi. Kenya 100 ml ea 2 N NaOH 'me u hlohlelletse ho fihlela e qhibiliha. Hlakola ka metsi ho 1000 ml ho fumana tharollo ea 0.1 N NaBrO.
