Lub npe Acids

  1. Ib qho polyatomic ion nrog cov lus "-ate" siv cov lus "-ic" ua ib qho kua qaub .
  2. Thaum koj muaj ib tug polyatomic ion nrog ib qho oxygen ntau dua li "-ate" ion , tiam koj kua qaub yuav muaj prefix "per-" thiab cov lus "-ic." Piv txwv li, chlorate ion yog ClO3.

Raws li txoj cai, 3 txoj cai rau npe cov kua qaub yog dab tsi?

Lub npe Acids

  • Thaum lub anion xaus rau hauv -ide, lub npe acid pib nrog prefix hydro-.
  • Thaum lub anion xaus rau hauv -ate, lub npe ntawm cov kua qaub yog lub hauv paus ntawm anion ua raws li cov lus -ic.
  • Thaum lub anion xaus rau hauv -ite, lub npe ntawm cov kua qaub yog lub hauv paus ntawm anion ua raws li cov lus -ous.

Tsis tas li ntawd, polyatomic ions siv rau dab tsi? Polyatomic ions yog ions uas muaj ntau tshaj ib lub atom. Piv txwv li, nitrate ion , NO3-, muaj ib tug nitrogen atom thiab peb oxygen atoms. Cov atoms hauv a polyatomic ion feem ntau yog covalently bonded rau ib leeg, thiab yog li ntawd nyob ua ke raws li ib leeg, them unit.

Ib yam li ntawd, koj tuaj yeem nug, cov piv txwv ntawm polyatomic ions yog dab tsi?

Tseeb tiag, feem ntau ionic cov tshuaj muaj polyatomic ions . Paub zoo piv txwv yog sodium hydroxide (NaOH) nrog OH- raws li cov polyatomic anion, calcium carbonate (CaCO3), thiab ammonium nitrate (NH4TSIS MUAJ3), uas muaj ob polyatomic ions : NH+ thiab NO3-.

Koj puas muab prefixes rau polyatomic ions?

Polyatomic ions muaj npe tshwj xeeb. Ntau ntawm lawv muaj cov pa oxygen thiab hu ua oxyanions. Thaum sib txawv oxyanions yog ua los ntawm tib lub caij, tab sis muaj ntau cov pa oxygen atoms, ces ua ntej thiab suffixes yog siv los qhia lawv sib nrug. chlorine tsev neeg ntawm ions yog ib qho piv txwv zoo heev.
