Chidziwitso chaching'ono ndi chidziwitso chachikulu 丨 Phunziro la chitsanzo chonse cha phosphorous standard configuration

Kukhazikitsa zitsanzo zokhazikika ndi chinthu chomwe chiyenera kuchitika pafupipafupi panthawi yoyesera. Potengera chitsanzo cha kuyesa kokhudzana ndi zizindikiro zoyesera khalidwe la madzi, pokonza zitsanzo zokhazikika, poyerekeza mtengo woyesedwa ndi mtengo wofotokozera wa chitsanzo chokhazikika, munthu akhoza kudziwa ngati cholakwika cha chida choyesera chili mkati mwa mulingo womwe watchulidwa, ndipo winayo akhoza kutsimikizira ngati njira yoyezera ya woyeserayo ndi yolondola. Chifukwa chake, kukhazikitsa zitsanzo zokhazikika ndikofunikira kwambiri pa kudalirika kwa kuyesako.
Zotsatirazi zikuwonetsani njira yokhazikitsira chitsanzo chonse cha phosphorous, bwerani mudzaone.
Gawo loyamba ndikukonzekera zinthu zapadera za Lianhua Technology za phosphorous-potassium dihydrogen phosphate (KH2PO4), madzi osungunuka, beaker, stirging rod, ndi 1000mL volumetric flask musanayike.
Gawo lachiwiri ndikutenga pang'ono potaziyamu dihydrogen phosphate (KH2PO4) ndikuumitsa pa 110℃ kwa maola awiri, ndikuutulutsa utazizira.
Gawo lachitatu ndikuyezera molondola 0.2197 g ya potaziyamu dihydrogen phosphate youma (KH2PO4) ndikuyiyika mu beaker, onjezerani pafupifupi 100 ml ya madzi osungunuka, sakanizani mpaka itasungunuka kwathunthu, kenako onjezerani 5 mL ya analytical grade sulfuric acid, kenako muyiike mu botolo la volumetric (beaker ikhoza kutsukidwa katatu ndi madzi osungunuka, ndipo yankho lotsuka limawonjezeredwanso ku botolo la volumetric), ndipo potsiriza muchepetse kufika 1000 mL.
Tsopano, chitsanzo chonse cha phosphorous cha 50 mg/L chakonzeka. Chitsanzo chokhazikika chokonzedwacho chingagwiritsidwe ntchito kuyesa ndikuwongolera zida, ndipo nthawi yosungira nthawi zambiri imakhala miyezi 6.
Njira yokonzera chitsanzo chonse cha phosphorous chomwe chili pamwambapa ndi iyi. Nditsateni kuti mudziwe zambiri zokhudza kuyesa!
