Kukū o rongoā

Kukū o rongoā - he ariā tino noa e rua i roto i te revolution pūtaiao, me i roto i te papakupu whare - faaite te hanganga ine o te hanganga o tetahi otinga. I roto i runga ki te paerewa, me ngā whakamāramatanga IUPAC (International Rēhita o pūhui matū) i te kukū pā ki te ōwehenga taimaha o te taonga, me te otinga. whakamana te inenga o tenei ōwehenga i roto i ngā wae o te kamiriona / L g / L. ranei

Ki te whakaaro tatou he taonga, e rahi taea te whakahuatia e te momo taua o uara (hei tauira, te taimaha ki te taimaha), whakaata ratou te ōwehenga whakaae matamata, engari i roto i te mahi atu whakamahi whānui ko te ariā riro rongoā kukū.

He maha ngā kōwhiringa ki nei ki te whakaata i te arotahi. Hoki rongoā e whakamahia ana te nuinga noa faaiteraa i roto i te hanganga otinga o te papatipu me te rōrahi (mo nga ringihanga) ōrau e taea faaite kukū i roto i kiore, ano, ka taea te faaite i te kukū o te rongoā i roto i te ritenga karamu. I roto i ētahi wā, te whakamahi kukū o te kōwhiringa whakaata mā titer molarity ngahuru ranei.

Tikanga, te kukū o te rongoā e kore e nei rapua e pū nui i roto i tona faaiteraa, e whakaatu ana ōrau i te taimaha. I reira, i reira tika tiketike, te huhu whakamahia, taitara, ranei te karamu-ritenga.

A, no te whakamahi i kia whakamahia te ōrau taimaha ture, kia rite ki nei te kukū o te faaiteraa tohua i roto i te taua waeine, hei tauira, e hia karamu o te taonga i roto i roto i te maha etahi o karamu o otinga. e kore e taea te ngā i roto i karamu me wae rōrahi whakaata (hei tauira: te maha o karamu o te taonga i roto i te 100 milliliters o otinga).

Hei tauira, ki te hiahia tatou ki te faaite i te hanganga o te 10% otinga o te tote konutai o tātai ai NaCl, na ko reira ki te kia matau kia e Kei roto i te otinga 100 karamu 10 karamu o te tote, me te 90 go o te wai. I roto i taua take, ki te hoatu te kukū e i roto i ngā wae o te ōrau matū taimaha (hei tauira, 25% otinga), me te hiahia ki te whakamahi i te nui o te otinga i ko reira rite he nui tohua o te taonga (hei tauira, 5 g), te otinga kia tangohia hoki papatipu (i roto i tenei tauira - ko 20 g).

He ona tātai ake mō ia whakaata kē kukū. Na, ki te mea te kukū ōrau o te otinga whakamahia, te tātai, ko te:

C = M1 / m, ai: M1 - papatipu o te taonga rewa i roto i te otinga, me te whakahuatia i roto i karamu ranei kirokaramu, m - papatipu o te otinga, faaite i roto i te taua wae.

whakaritea te kukū niho kauoro o pūhui i roto i te otinga e te tātai: C (M) = n / V, te wahi n - nui o taonga i roto i kiore, V - te rōrahi o te otinga i roto i te rita. Mā te whakamahi i karamu-ritenga tātai e te puka: C (N) = z / V, te wahi V - rōrahi o te otinga, faaite i roto i rita, z - maha o ōrite.

I roto i te wā i reira te kiato o te otinga mohiotia he watea atu ki te tohu i te reira i roto i te rōrahi. Ko Ko te take anake, ina tae mai te reira ki te tika rongoā takiwa (iti iho i te 1%), mai i te hapa i roto i tenei take, kia kia iti tenei.

Whakahuatia i roto i te maha o kiore o te kukū i roto i te matū huaina kiore. Ki te mea koe, "otinga titiwha", te auraa e roto 1 rita o te wai 1 kamiriona o te taonga. huaina te otinga taua ko te "titiwha".

Ki te te kukū faaite rite maha o karamu-taurite, e Kei roto i roto i te kōwae ako rōrahi o te wai, i roto i tenei take, he whakapuaki "normality", e tohu e, mo te tauira, i roto i te 1 rita o te wai ko 1 karamu ōrite. Nuinga o ngā wā, kua karangatia e noa te otinga taua noa.

te mahi te tuhinga ki anake etahi o nga tikanga matua o te faaite kukū. I roto i te tahi atu wā, ka tae mai te reira ki rongoā matatini, a taea te whakamahi i ētahi atu wae mo tenei whakaaro.
