Qhov sib txawv tseem ceeb ntawm inorganic phosphate (Pi) thiab pyrophosphate (PPi) yog cov inorganic phosphate tebchaw tuaj yeem pom raws li ib pawg phosphate txuas rau hlau cation(s) whereas pyrophosphates tuaj yeem pom raws li ob pawg phosphate txuas rau txhua tus. Lwm yam los ntawm kev sib txuas ntawm P-O-P thiab cov anion no cuam tshuam nrog hlau cation(s).
Phosphates yog inorganic compounds. Muaj ntau hom phosphates, suav nrog diphosphates, orthophosphates, pyrophosphates, thiab lwm yam.
Dab tsi yog Inorganic Phosphate (Pi)?
Inorganic phosphates yog ntsev ntawm phosphoric acid. Hauv cov tebchaw no, peb tuaj yeem pom ib pawg phosphate txuas nrog cov hlau cation. Yog li ntawd, pawg phosphate ua raws li anion. Tag nrho cov nqi ntawm no anion yog -3. Qhov no qhia tau hais tias qhov no anion tuaj yeem koom nrog hauv kev tsim cov monobasic, dibasic, thiab tribasic ntsev. Cov pab pawg phosphate muaj cov txheej txheem tetrahedral. Inorganic phosphates tshwm sim raws li cov ntsev ntawm pab pawg 1 hais. Piv txwv li: sodium (Na), poov tshuaj (K), calcium (Ca), thiab lwm yam.
Daim duab 01: Cov Qauv Tshuaj ntawm Phosphate Anion
Ob qhov loj inorganic phosphate tebchaw yog orthophosphates thiab condensed phosphates. Ntawm lawv, orthophosphates yog reactive heev, thiab cov no yog cov yooj yim inorganic phosphates. Lawv tsuas muaj ib chav phosphate ib molecule. Condensed phosphates muaj ntau tshaj ib chav tsev phosphate. Cov tebchaw no tseem muaj txiaj ntsig zoo li chiv, xws li: superphosphate thiab triple superphosphate.
YPyrophosphate (PPi) yog dab tsi?
Pyrophosphate yog phosphorous oxyanion uas muaj ob lub phosphorous atoms nyob rau hauv daim ntawv ntawm P-O-P linkage. Muaj ntau ntau yam pyrophosphate ntsev, nrog rau disodium pyrophosphate thiab tetrasodium pyrophosphate. Peb tuaj yeem piav qhia txog pyrophosphate li diphosphate ib yam nkaus vim nws zoo li ob pawg phosphate txuas rau ib leeg. Ntxiv mus, cov niam txiv pyrophosphate molecules yog muab los ntawm ib nrab los yog ua tiav neutralization ntawm pyrophosphoric acid.
Daim duab 02: Cov Qauv Tshuaj ntawm Pyrophosphate
Peb tuaj yeem npaj pyrophosphate compound los ntawm cua sov phosphates. Txawm li cas los xij, pyrophosphate ntsev yog kev lag luam tsim los ntawm phosphoric acid mus rau qhov twg qhov kev sib xyaw ua ke tshwm sim. Tsis tas li ntawd, cov tshuaj no feem ntau tshwm sim dawb los yog tsis muaj xim. Ntawm cov ntsev no, pyrophosphates txuam nrog alkali hlau yog cov dej-soluble tshuaj. Tsis tas li ntawd, cov ntsev no yog ib qho tseem ceeb ua cov neeg ua haujlwm rau cov hlau ions. Yog li, pyrophosphates muaj ntau daim ntawv thov tseem ceeb hauv kev lag luam tshuaj.
Qhov txawv ntawm Inorganic Phosphate (Pi) thiab Pyrophosphate (PPi) yog dab tsi?
Inorganic phosphates yog ntsev ntawm phosphoric acid. Hauv cov tebchaw no, peb tuaj yeem pom ib pawg phosphate txuas nrog cov hlau cation. Pyrophosphate yog ib qho phosphorous oxyanion uas muaj ob lub phosphorous atoms nyob rau hauv daim ntawv ntawm P-O-P linkage. Qhov sib txawv tseem ceeb ntawm inorganic phosphate (Pi) thiab pyrophosphate (PPi) yog tias cov tshuaj inorganic phosphate tuaj yeem pom raws li pawg phosphate txuas rau hlau cation(s), whereas pyrophosphates tuaj yeem pom raws li ob pawg phosphate txuas rau ib leeg los ntawm P-O-P. linkage thiab anion yog txuam nrog hlau cation(s).
Cov lus hauv qab no nthuav tawm qhov sib txawv ntawm inorganic phosphate (Pi) thiab pyrophosphate (PPi) kom ntxaws.
Summary – Inorganic Phosphate (Pi) vs Pyrophosphate (PPi)
Inorganic phosphates thiab pyrophosphates yog ob yam sib txawv ntawm phosphates derived compounds. Qhov sib txawv tseem ceeb ntawm inorganic phosphate (Pi) thiab pyrophosphate (PPi) yog tias cov tshuaj inorganic phosphate tuaj yeem pom raws li pawg phosphate txuas rau hlau cation(s), whereas pyrophosphates tuaj yeem pom raws li ob pawg phosphate txuas rau ib leeg los ntawm P-O-P. linkage thiab anion yog txuam nrog hlau cation(s).
