Mmiri a na-eji na usoro ule ga-ezo aka na mmiri na-ekpo ọkụ ma ọ bụ mmiri na-adịghị mma ma ọ bụrụ na ọ dịghị ihe ọzọ a chọrọ. Mgbe akọwapụtaghị ihe mgbaze nke ngwọta, ọ na-ezo aka na ngwọta mmiri. Mgbe kpọmkwem ịta nke H2SO4, HNO3, HCL na NH3 · H2O na-adịghị kpọmkwem na ule usoro, niile na-ezo aka ịta nke azụmahịa dị reagent nkọwa. Mbelata nke mmiri mmiri na-ezo aka n'ókè nke mwụda mmiri a na-ekpo ọkụ na-esi na dropper ọkọlọtọ, nke ya na 1.0ml na 20 Celsius C.

Enwere ike igosipụta itinye uche na ngwọta n'ụzọ ndị a:
â  Na mkpokọta mkpokọta (ya bụ, ntinye nke ihe) : akọwara ya dị ka ọnụọgụ ihe nwere solute n'ime otu olu nke ngwọta, otu ahụ bụ Mol/L.

â¡ N'ihe dị ka ịta: ya bụ, n'ọtụtụ siri ike reagent agwakọta uka ma ọ bụ mmiri mmiri reagent agwakọta olu nọmba, nwere ike dee dị ka (1 1) (4 2 1) na ndị ọzọ ụdị.

⢠Na akụkụ nke uka (olu): na solute e depụtara maka akụkụ nke oke ma ọ bụ akụkụ olu nke okwu ngwọta, enwere ike ịpụta dị ka w ma ọ bụ Phi.

(4) Ọ bụrụ na a na-egosipụta ntinye ihe ngwọta na nkeji nke oke na ikike, enwere ike ịkọwa ya dị ka g / L ma ọ bụ site na ya kwesịrị ekwesị (dị ka mg / mL).

Ihe achọrọ na ihe ndị ọzọ achọrọ maka nkwadebe nke ngwọta:
Ịdị ọcha nke reagents na ihe mgbaze na-eji na nkwadebe nke ngwọta kwesịrị izute ihe achọrọ nke ihe nyocha. A na-echekwa reagents n'ozuzu n'ime karama iko siri ike, a na-echekwa ihe ngwọta lye na metal na karama polyethylene, na-echekwa reagents foto na karama agba aja aja.

A ga-emerịrị ule ndị yiri ya na nyocha. Ngosipụta nke nsonaazụ nyocha kwesịrị ịdị na-anọchi anya ụkpụrụ ịdị ọcha nri, yana ngụkọta na uru nke data kwesịrị ịgbaso iwu nke ọnụ ọgụgụ dị ịrịba ama na iwu nke nhọrọ ọnụọgụ.

A ga-eme usoro nyocha ahụ n'ụzọ siri ike dabere na usoro nyocha akọwapụtara na ọkọlọtọ, a ga-emekwa usoro nchebe megide ihe ndị na-adịghị ize ndụ (nsi, mgbawa, corrosion, ọkụ, wdg) na nnwale ahụ. Ụlọ nyocha nyocha anụ ahụ na nke kemịkalụ na-emejuputa njikwa ogo nyocha. Dabere na nguzobe nke nkọwa teknụzụ dị mma, usoro mkpebi kwesịrị inwe oke nchọta, nkenke, izi ezi, ịbịaru data curve ọkọlọtọ na paramita teknụzụ ndị ọzọ. Ndị nyocha kwesịrị dejupụta ndekọ nyocha.
