Ubkpa ya mmiri bụ ihe ejiri ya gbanye na mmiri ma ọ bụ ihe ọzọ. Ma ihe siri ike ma mmiri mmiri na gaseous ihe nwere ike igbari na mmiri. Site na solubility, a na-eke ihe niile ụzọ atọ:
- ukwuu soluble
- obere soluble
- insoluble
Ekweghi insoluble ihe adighi adi, ya mere aha insoluble bu ihe eji acho ya, ikwesiri iguta "ihe insoluble".
Ngwakọta nke ihe bekee na-agbanwe na ọnọdụ okpomọkụ dabere na ọnọdụ okpomọkụ na nrụgide, dịka ọmụmaatụ, ihe dị na KNO3 (potassium nitrate) na okpomọkụ nke + 20 Celsius C nwere solubility nke 31.6 g / 100 g mmiri, yana nju mmiri + 100 ° C - 245 g / 100 g nke mmiri.
Solubility, ọdịda na hydrolysis nke nnu n'okpuru ọnọdụ nkịtị
Nkọwa maka tebụl:
- P - nnu bụ soluble (karịa 0.1 mol / l),
- M - nnu na-egbu mmiri (0.1-0.001 mol / l),
- N - nnu enweghị atụ (ihe na-erughị 0.001 mol / l),
- [H] - hydrolysis a na-apụghị ịgbagha agbagha, nnu adịghị eme ka mmiri ahụ kwụsị, nnu nnu bụ isi na mwepụta carbon dioxide, Cr.2S3 - precipitates Cr (OH)3 na mwepụta hydrogen sulfide,
- + - nnu riri mmiri kpamkpam,
- - - adighi adi,
- * P - a gbanyere mkpọrọgwụ site na mkpọchi,
- P * - a na - egwu mmiri site na anion.
Ngwọta nke nnu
Nkọwa maka tebụl
- 1 - nnu dị mmiri n'ụdị,
- 2 - ubé soluble na mmiri,
- 3 - insoluble na mmiri, mana soluble na organic na ịnweta asịd,
- 4 - insoluble na mmiri na Organic acid, ma soluble na mineral acid,
- 5 - nnu adịghị asoụ mmiri ma ọ bụ na acid,
- 6 - hydrolyzed.
