Pehea e hoʻāʻo ai i ka hoʻohui ʻana o nā mea inorganic i nā mea kōkua hana ACR?

Ke ʻano ʻike no Ca2+:

Nā mea hana hoʻokolohua a me nā reagents: nā kīʻaha; ʻŌmole conical; Funnel; Burette; Umu uila; Ethanol anhydrous; Waikawa hydrochloric, hopena buffer NH3-NH4Cl, hōʻailona calcium, hopena maʻamau 0.02mol/LEDTA.

Nā ʻanuʻu hoʻāʻo:
1. E kaupaona pono i kahi nui o ka hāpana kōkua hana ACR (pololei i 0.0001g) a waiho i loko o kahi kīʻaha. E hoʻomaʻū iā ia me ka ethanol anhydrous, a laila e hoʻohui i ka nui o ka waikawa hydrochloric 1:1 a hoʻomehana iā ia ma luna o ka umu uila e ʻae i nā ion calcium e hana piha me ka waikawa hydrochloric;
2. E holoi me ka wai a kānana me kahi funnel e loaʻa ai kona wai moakaka;
3. E hoʻoponopono i ka waiwai pH i ʻoi aku ma mua o 12 me ka hoʻohana ʻana i ka hopena buffer NH3-NH4Cl, e hoʻohui i kahi nui kūpono o ka calcium indicator, a titrate me ka hopena maʻamau 0.02mol/LEDTA. ʻO ka hopena ka wā e loli ai ke kala mai ka ʻulaʻula poni a i ka uliuli maʻemaʻe;
4. E hana i kahi hoʻāʻo hakahaka i ka manawa like;
5. E helu iā C # a2+=0.02 $(V-V0) $0.04004M $%&&
V - Ka nui o ka hopena EDTA i hoʻopau ʻia i ka wā e hoʻāʻo ai i nā laʻana kōkua hana ACR (mL).
V # – Ka nui o ka hopena i hoʻopau ʻia i ka wā o ka hoʻāʻo hakahaka
M — E kaupaona i ke kaumaha o ka hāpana kōkua hana ACR (g).

ʻAno puhi no ke ana ʻana i nā mea inorganic:
Nā mea hana hoʻokolohua: ke kaulike kālailai, ka umu muffle.
Nā ʻanuʻu hoʻāʻo: E lawe i nā laʻana kōkua hana ACR 0.5,1.0g (pololei i 0.001g), e kau iā lākou i loko o ka umu muffle mahana mau 950 a puhi no 1 hola, a laila e hoʻomaʻalili a kaupaona e helu i ke koena o nā mea i puhi ʻia. Inā hoʻohui ʻia nā mea inorganic i ka laʻana o nā kōkua hana ACR, e nui aʻe ke koena.
ʻAno hana hoʻoheheʻe:
1. Nā mea hana hoʻokolohua a me ke kaulike loiloi reagent; ʻōmole volumetric 25mL; Trichloromethane.
KaʻAnuʻu Hana 2: Wahi a ke ʻano hoʻāʻo ʻana o ka viscosity intrinsic ACR, e kaupaona i 75mg o ka hāpana a waiho i loko o kahi ʻōmole volumetric 25mL. E hoʻohui i ka mea hoʻoheheʻe trichloromethane. Inā he turbidity a i ʻole ka mālamalama ʻike ʻia
