Tautuhinga-
A: Whakangao Infrared <197K>.
B: Ki te 5 mL o te wairewa (1 i roto i te 10) tāpirihia te 5 mL o te pākawa hiriwa TS: he ma, he wairere wairewa, he wairewa i roto i te haukinia hydroxide engari kare e rewa i te waikawa nitric, ka hanga.
Awhe whakarewa, Class I <741>: i waenganui i te 149 me te 152.
Kawakawa-Whakarewa 100 mg ki te 10 mL o te wai kohuatia, me te tapiri i te 1 topata o te bromothymol blue TS: kaua e neke ake i te 0.50 mL o te 0.010 N konutai hydroxide e hiahiatia ana kia puta he huringa tae.
Ngaronga i runga i te whakamaroke <731>-Ka whakamaroke ki te 105 mo te 3 haora: kaua e ngaro ake i te 1.0% o tona taumaha.
Te toenga i runga i te mura <281>: kaua e neke ake i te 0.2%.
Ko te ihirangi pūhaumāota- Whakawhitihia te 280 mg, ka tika te pauna, ki te porcelain casserole, ka tapirihia te 140 mL wai me te 1 mL o te dichlorofluorescein TS.Whakaranuhia, ka titrate ki te 0.1 N te pākawa hiriwa VS kia pupuhi te pūhaumāota hiriwa ka whiwhi te ranunga ki te tae māwhero.Ko ia mL o te 0.1 N te pākawa hiriwa he rite ki te 3.545 mg o Cl.Ka kitea kia kaua e iti iho i te 19.3%, kaua hoki e neke ake i te 19.8% o Cl.
Whakamaatau-A tika te pauna mo te 400 mg o Acetylcholine Chloride, ka memeha ki roto i te 15 mL wai i roto i te ipu koeko kua mau ki te karaihe.Tāpirihia te 40.0 mL o te 0.1 N konutai waihā VS, ka whakamahana i runga i te pati korohū mō te 30 meneti.Kōkuhutia te pū, tukua kia whakamatao, tāpirihia te phenolphthalein TS, ka titrate i te taikaha kawakore ki te 0.1 N waikawa pungatara VS.Whakaritehia he whakatau patea (tirohia nga Titration toenga i raro i te Titrimetry 541).Ko ia mL o te 0.1 N konutai waikawa he rite ki te 18.17 mg o C7H16ClNO2.
