5. Saray Subok:
1. Formic Acid:
a. Pamaakaran: Timbangen so manga 5 g na sample (ya usaren so teknikal a timbangan) ed 100 ml a beaker. Ilaktip so 2 tedter na phenolphthalein indicator solution tan neutralize na 2 N NaOH ya solusyon anggad ompatnag ya ambalanga so kolor to. I-evaporate ed water bath ya anggad kapaldua na orihinal ya karakel. Palemewen, pa-asidoan na 5 ml na concentrated HCl, tan iyalis ed 250 ml ya iodine flask ya walay 50 ml na danum tan 50 ml na 0.1 N NaBrO solution. Isara ya malet, ilaok ya maong, tan paulyanan ya onalagey ed loob na 30 minutos. Ilaktip so 15 ml na 16.5% KI solution, 20 ml na 6 N HCl, tan 2 ml na starch indicator solution. I-titrate so 0.1 N Na2S2O3 ya solusyon anggad naandi so kolor ya asul (sampot). Manggawa na blankon test ya mankakasakey.
b. Kalkulasyon: (Blanko ml – Sample ml) × 0.1 (Normality) × 0.02301 = gramo na HCOOH
c. Grade Glacial Acetic Tandaan: Say pangipainit ed water bath kayari na pangiyarum na NaOH et parad pan-evaporate tan pangekal na acetaldehyde, ya no andi et pansengegan na atagey iran resulta.Grade Glacial Acetic.
2. Acetaldehyde:
a. Paraan: Timbangen so manga 10 g na glacial acetic acid (ya usaren so teknikal a timbangan) ed 250 ml ya iodine flask. Mangiyan na 50 ml na danum, insan i-pipette so eksakton 10 ml na 4% NaHSO3 ya solusyon ed flask. Isara ya malet, yugyogen, tan paulyanan ya onalagey ed loob na 30 minutos. Ilaktip so 2 ml na starch indicator solution tan i-titrate na 0.1 N Iodine solution anggad ompaway so kolor ya asul (sampot). Manggawa na blankon test ya mankakasakey.
b. Kalkulasyon: (Blanko ml – Sample ml) × 0.1 (Normality) × 0.02203 = gramo na CH3CHO
6. Panagparaan na Reagent:
0.1 N Sodium Hypobromite (NaBrO) Solution: Ilaktip so 2.8 ml na bromine ed 500 ml na danum. Ilaktip so 100 ml na 2 N NaOH tan igalaw anggad natunaw. I-dilute ed danum ya anggad 1000 ml pian naala so 0.1 N NaBrO ya solusyon.
6. Grado na Panagparaan na Glacial Acetic Reagent:
0.1 N Sodium Hypobromite (NaBrO) Solution: Ilaktip so 2.8 ml na bromine ed 500 ml na danum. Ilaktip so 100 ml na 2 N NaOH tan igalaw anggad natunaw. I-dilute ed danum ya anggad 1000 ml pian naala so 0.1 N NaBrO ya solusyon.
