Solubility yog cuam tshuam los ntawm pH Los ntawm hloov pH ntawm cov tshuaj, koj tuaj yeem hloov lub xeev tus nqi ntawm cov kua nplaumYog tias pH ntawm cov tshuaj yog xws li cov molecule tshwj xeeb nqa. tsis muaj net hluav taws xob them, cov kuab tshuaj feem ntau muaj tsawg solubility thiab precipitates tawm ntawm cov tshuaj.
pH cuam tshuam li cas rau solubility?
Rau cov ionic tebchaw uas muaj cov anions yooj yim, solubility nce raws li pH ntawm cov tshuaj txo. Rau cov ionic tebchaw uas muaj anions ntawm qhov tseem ceeb negligible (xws li conjugate bases ntawm muaj zog acids), solubility yog unaffected los ntawm kev hloov nyob rau hauv pH.
Yuav ua li cas rau solubility thaum pH nce?
Zn(OH)2 yog lub hauv paus sparingly soluble. Yog tias koj nce pH los ntawm kev ntxiv OH- ions, Le Châtelier Txoj Cai hais tias txoj haujlwm ntawm kev sib npaug yuav txav mus rau sab laugLub solubility ntawm Zn (OH) 2 txo. Yog tias koj txo cov pH los ntawm kev ntxiv H3O + ions, ntxiv H3O + ions yuav hnov mob nrog OH- ions thiab tsim dej.
acid nce solubility li cas?
Cov nyhuv ntawm Acid-Base Equilibria lub Solubility ntawm ntsev. Raws li ntau cov kua qaub ntxiv rau kev ncua ntawm Mg(OH) 2 , qhov sib npaug pom nyob rau hauv Equation 16.4. 6 yog tsav mus rau sab xis, ntau Mg(OH)2 dissolves. … Sparingly soluble ntsev tau los ntawm cov kua qaub uas tsis muaj zog yuav ua rau ntau dua soluble hauv cov kua qaub.
Puas hloov pH ntawm cov tshuaj cuam tshuam rau solubility ntawm cov protein?
Rau tag nrho cov ntsev kuaj, protein solubility nce thaum pH nce(Table 2). Qhov siab tshaj plaws ntawm cov protein solubility tau pom ntawm pH8. 0 vim tias nyob rau hauv cov xwm txheej no, cov protein zoo thiab qhov tsis zoo ntawm cov khoom siv molecules cuam tshuam nrog dej ntau dua. Protein solubility yog qis hauv acidic pH dua li alkaline pH.
