Defining Polyprotic Weak Acids H ₂A is a diprotic acid vim nws tuaj yeem pub 2 protons. H _{2A yog cov kua qaub uas tsis muaj zog vim nws tsis ua kom tiav (ionise), uas yog, daim ntawv molecular ntawm cov kua qaub nyob rau hauv qhov sib npaug nrog cov ions uas tsim los ntawm nws ib nrab dissociation.}

YPuas Polyprotic acids ntau acidic?

Polyprotic acids, zoo li H2 SO4 thiab H3 PO4, muaj ob lossis peb lub hydrogen ions. Nws yog kev ntxias kom xav tias polyprotic acid yog muaj zog dua li monoprotic acids vim tias lawv muaj ntau yam hydrogen ions, tab sis qhov tseeb tsis muaj tseeb.

Koj tuaj yeem qhia tau li cas tias polyprotic acid muaj zog dua?

Nco ntsoov: Cov kua qaub uas muaj zog tshaj plaws dissociate yooj yim tshaj plaws. Ntawm cuaj cov kua qaub uas tau teev tseg hauv Cov Lus, qhov muaj zog tshaj plaws yog sulfuric (1) , nrog cov kua qaub ionization siab tshaj plaws, thiab qhov tsis muaj zog tshaj plaws yog phosphoric (3). ions yog tam sim no nyob rau hauv me me concentrations., thiab H ^{+ nyob rau hauv kev txiav txim kom txo qis concentration.}

YPuas Diprotic acids muaj zog acids?

Diprotic acids, xws li sulfuric acid (H ₂ SO ₄), carbonic acid (H ₂ CO₃), hydrogen sulfide (H₂S), chromic acid (H₂ CrO₄), thiab oxalic acid (H₂C₂O₄) muaj ob lub acidic hydrogen atoms. … Sulfuric acid yog a muaj zog acid vim K_{a rau qhov poob ntawm thawj proton ntau dua 1.}

Yog HCl tsis muaj zogacid?

HCl yog a muaj zog acid vim nws dissociates yuav luag tag. Los ntawm qhov sib txawv, cov kua qaub tsis muaj zog zoo li acetic acid (CH ₃ COOH) tsis cuam tshuam zoo hauv dej - ntau H⁺ ions nyob twj ywm hauv cov molecule. Hauv cov ntsiab lus: qhov muaj zog cov kua qaub ntau H^{+ ions raug tso rau hauv kev daws.}
