Kedu otu esi anwale mgbakwunye nke ihe ndị na-adịghị na organic na ihe enyemaka nhazi ACR?

Usoro nchọpụta maka Ca2+:

Ngwa nnwale na ihe ndị e ji eme ihe: beakers; karama conical; Funnel; Burette; Ọkụ ọkụ eletrik; ethanol anhydrous; Hydrochloric acid, NH3-NH4Cl ihe nchekwa nchekwa, ihe ngosi calcium, ihe ngwọta ọkọlọtọ 0.02mol/LEDTA.

Usoro nnwale:
1. Tụọ nke ọma nha nke ihe nlele ACR (nke ziri ezi ruo 0.0001g) ma tinye ya n'ime beaker. Jiri ethanol anhydrous mee ya mmiri, wee tinye ihe karịrị 1:1 hydrochloric acid ma kpoo ya ọkụ n'elu ọkụ eletrik iji mee ka ion calcium meghachi omume nke ọma na hydrochloric acid;
2. Jiri mmiri saa ahụ ma jiri ihe e ji ekpofu ihe sachaa ya ka o wee nweta mmiri doro anya;
3. Gbanwee uru pH ka ọ bụrụ ihe karịrị 12 site na iji ihe ngwọta nchekwa NH3-NH4Cl, tinye ego kwesịrị ekwesị nke ihe ngosi calcium, wee titrate ya na ihe ngwọta ọkọlọtọ 0.02mol/LEDTA. Isi njedebe bụ mgbe agba ahụ gbanwere site na ọbara ọbara odo odo gaa na acha anụnụ anụnụ dị ọcha;
4. Mee ule efu n'otu oge;
5. Gbakọọ C # a2+=0.02 $(V-V0) $0.04004M $%&&
V - Olu nke ngwọta EDTA e riri mgbe a na-anwale ihe nlele enyemaka nhazi ACR (mL).
V # - Olu nke ihe ngwọta e ji mee ihe n'oge ule efu
M — Tụọ oke nke ihe nlele enyemaka nhazi ACR (g).

Usoro ọkụ maka ịtụ ihe ndị na-adịghị n'ime ahụ:
Ngwa nnwale: nguzozi nyocha, ọkụ muffle.
Usoro nnwale: Were ihe nlele enyemaka nhazi ACR nke 0.5,1.0g (nke ziri ezi ruo 0.001g), tinye ha n'ime ọkụ ọkụ nke nwere okpomọkụ 950 na-agbanwe agbanwe ma gbaa ha ọkụ ruo otu awa, wee jụọ oyi ma tụọ ihe fọdụrụnụ iji gbakọọ ihe ọkụ ahụ. Ọ bụrụ na etinyere ihe ndị na-adịghị ndụ na ihe nlele nke ihe nhazi ACR, a ga-enwe ihe fọdụrụ karịa.
Usoro ihe mgbaze:
1. Ngwa nnwale na nhazi nyocha ihe ndị na-eme ihe; 25mL volumetric flask; Trichloromethane.
Nzọụkwụ nke 2: Dịka usoro nnwale viscosity nke ACR si dị, tụọ 75mg nke ihe nlele ahụ wee tinye ya na karama volumetric 25mL. Tinye ihe mgbaze trichloromethane. Ọ bụrụ na e nwere turbidity ma ọ bụ ìhè a na-ahụ anya
