3. Te Whakatau i te Ihirangi Pūmua Konupūmā
3.1 Tirohanga Whānui mō te Tikanga Konupūmā Formate: I roto i tētahi otinga konupūmā formate kawakore paku, tāpirihia he nui rawa o te otinga paerewa pāhare pākawa waro. Whakamahanahia kia tino oti te tauhohenga waikura. Mā te nui rawa o te pāhare pākawa waro ka tukuna te iodine mai i te pāhare pākawa iodide i roto i tētahi otinga waikawa, kātahi ka titrated ki te otinga paerewa konutai thiosulfate.
3.2 Ngā Hipanga Whakatau i te Konupūmā Formate: Taumahahia te 0.4g o te tauira konupūmā formate (tika ki te 0.0002g), whakanohoia ki roto i tētahi ipu rōrahi 250ml, whakarewahia ki te wai, whakaranua kia tae ki te tohu, ka rūrū pai. Tāpirihia te 25.00ml (10ml rānei) o tēnei otinga ki roto i tētahi ipu iodine, tāpirihia te 0.2g o te konutai kāponāte kore wai, ka rūrū pai. Tāpirihia te 50.00ml (20ml rānei) o te otinga paerewa pāhare pākawa, whakamahanahia ki roto i te kaukau wai mō te 30 meneti, kātahi ka whakamatao. Tāpirihia te 6ml o te otinga waikawa whanariki me te 2g o te pāhare pākawa iodide, waiho kia tū i te pōuri mō te 5 meneti. Whakamātautauhia ki te otinga paerewa konutai thiosulfate; tata ki te pito, tāpirihia te 3ml o te tohu māngaro (0.5%), ka haere tonu te whakamātautau kia ngaro ra ano te tae kikorangi. Whakahaerehia he whakamātautau pātea i te wā kotahi.
