Alkalis yog ib txwm dej-soluble, txawm tias qee qhov zoo li barium carbonate tsuas yog soluble thaum reacting nrog cov kua qaub aqueous.
Vim li cas alkalis soluble hauv dej?
-Ib qho muaj zog alkali dissociates tag nrho raumuab hydroxyl ions thaum lub zog alkali dissociates ib feem los muab cov hydroxyl ions. Piv txwv li. Sodium hydroxide yog alkali muaj zog thaum aqueous ammonia yog alkali tsis muaj zog. - Bass soluble hauv dej hu ua alkali.
YPuas yog alkali thiab acid yaj hauv dej?
Ib qho kua qaub yog ib yam khoom uas tsim cov hydrogen ions, H +(aq) , thaum yaj hauv dej. Ib qho alkali yog ib yam khoom uas tsim hydroxide ions, OH -(aq), thaum yaj hauv dej. (Cov qib siab dua) Cov kua qaub muaj zog tag nrho ionise hauv dej.
Yuav ua li cas soluble hauv dej hu ua alkalis?
Teb: Cov hauv paus uas soluble hauv dej yog hu ua alkalis. Ob qho piv txwv yog NaOH thiab KOH, sodium hydroxide thiab potassium hydroxide.
Puas alkalis soluble hauv dej?
Alkalis yog ib txwm dej-soluble, txawm tias qee qhov zoo li barium carbonate tsuas yog soluble thaum reacting nrog cov kua qaub aqueous.

Puas yog nag lossis daus soluble hauv dej?
Precipitates yog insoluble ionic khoom khoom ntawm cov tshuaj tiv thaiv, tsim thaum qee cov cations thiab anions ua ke hauv cov tshuaj aqueous. Qhov kev txiav txim siab ntawm kev tsim cov nag lossis daus tuaj yeem sib txawv . Puas nag los yaj hauv dej?
Puas yog hentriacontane soluble hauv dej?
Hentriacontane yog ib qho hydrophobic molecule, insoluble hauv dej, thiab siab nruab nrab . Hentriacontane siv rau dab tsi? CHEBI:5659 - hentriacontane Ib yam khoom uas kills lossis slows kev loj hlob ntawm Mycobacterium tuberculosis thiab yog siv los kho tuberculosis .
Puas yog alkyl halides soluble hauv dej?
Alkyl halides muaj me ntsis kom tsis muaj solubility hauv dej txawm tias muaj cov pa roj carbon-halogen daim ntawv cog lus. Lub attraction ntawm alkyl halide molecules muaj zog tshaj qhov attraction ntawm alkyl halide thiab dej. Alkyl halides muaj me ntsis tsis muaj solubility hauv dej, tab sis yuav tsum paub txog qhov ntom ntom .
Puas yog triacylglycerols soluble hauv dej?
Triglycerides yog tag nrho insoluble hauv dej. Txawm li cas los xij, vim yog pawg ionic organic phosphate, phospholipids qhia cov khoom vim tias pawg ionic nyiam dej . Vim li cas triacylglycerols insoluble hauv dej? Triglycerides yog insoluble hauv dej vim lawv tsis muaj nqi piv txwv li lawv muaj covalent bonds… Triglycerides muaj polar (them) taub hau thiab tsis muaj polar fatty acid tails yog li tus nqi ntawm cov molecule yog unevenly faib.
Puas yog dej sodium soluble lossis rog soluble?
Vitamins yog cais raws li cov rog soluble (vitamin A, D, E thiab K) los yog dej soluble (vitamin B thiab C). Qhov sib txawv ntawm ob pawg no tseem ceeb heev. Nws txiav txim siab seb txhua cov vitamin ua li cas hauv lub cev. Cov vitamins muaj roj soluble yog soluble hauv lipids (fas) .
