Chemical Properties:

Phosphoric acid yog cov xim tsis muaj xim, tsis muaj ntxhiab, crystalline khoom lossis cov kua qaub tuab.Lub cev lub cev yog lub zog thiab qhov kub thiab txias nyob ntawm.
Concentrated phosphoric acid tshwm sim raws li tsis muaj xim, tsis muaj ntxhiab, syrupy kua.Nws muaj ib tug pleasing acid saj thaum haum diluted.
Pure phosphoric acid, tseem hu ua orthophosphoric acid, yog ib qho ntshiab, tsis muaj xim, ntxhia acid nrog lub zog me ntsis.Nws yog ib txwm ua lag luam raws li cov tshuaj aqueous ntawm 75-85% nyob rau hauv uas nws tshwm sim raws li ib tug ntshiab, viscous kua.
Khoom noj khoom haus qib phosphoric acid yog siv los acidify cov zaub mov thiab dej haus.Nws muab tangy los yog qaub saj thiab, yog ib tug loj-tsim tshuaj, yog muaj nyob rau hauv pheej yig thiab ntau ntau.Phosphoric acid, siv nyob rau hauv ntau yam dej qab zib, tau txuas mus rau txo cov pob txha ceev nyob rau hauv kev tshawb fawb epidemiological.Nyob rau hauv luv luv, phosphoric acid yog ib tug muaj zog acid thiab ib tug ntau muaj kev lag luam tshuaj siv nyob rau hauv lub tsim ntawm ib tug ntau ntawm cov khoom, tshwj xeeb tshaj yog porcelain thiab hlau ntxuav, detergents, thiab fertilisers.Nws kuj yog siv los ua khoom noj khoom haus thiab yog ib qho tseem ceeb ntawm ntau cov dej qab zib.Tsawg phosphate concentrations muaj nyob rau hauv cov dej haus uas nws ntxiv rau hauv qee qhov chaw kom txo tau cov hmoov lead solubility.

Daim ntawv thov:

Phosphoric acid yog qhov thib ob tsuas yog sulfuric acid raws li cov kua qaub ua lag luam thiab tsis tu ncua ranksin saum 10 cov tshuaj siv thoob ntiaj teb.States, tab sis nws yog siv nyob rau hauv ib tug xov tooj ntawm lwm yam kev siv.Phosphates tau siv los ua cov neeg tsim khoom thiab cov dej softeners.Tus neeg tsim khoom yog ib yam khoom ntxiv rau xab npum lossis tshuaj ntxuav tes kom ua kom lawv lub zog huv.
Phosphoric acid yog siv los ua ib qho nruab nrab hauv kev tsim cov khoom noj tsiaj, tshuaj kho dej, kho cov hlau saum npoo, etching tus neeg sawv cev, thiab cov khoom tu tus kheej xws li tshuaj txhuam hniav.Nws yog siv los ua catalyst hauv kev lag luam roj av thiab polymer.Phosphoricacid yog siv nyob rau hauv cov zaub mov raws li preservative, acidulant, thiab tsw enhancer;nws acidifies carbonateddrinks xws li Coca Cola thiab Pepsi, muab lawv ib tug tangy tsw.Phosphoric acid yog siv los ua arust remover thiab hlau ntxuav.Naval Jelly yog kwv yees li 25% phosphoric acid.Lwm cov kev siv rau phosphoric acid suav nrog kev tswj qhov pom ntawm cov iav ntau lawm, textile dyeing, roj hmab latexcoagulation, thiab kho hniav cements.
Phosphoric acid (H3PO4) yog qhov tseem ceeb tshaj plaws oxoacid ntawm phosphorus thiab nws txoj kev siv tseem ceeb yog hauv kev tsim cov chiv.
Nyob rau hauv tib neeg lub cev, phosphate yog lub ntsiab phosphorus-muaj compound.Phosphate yog ib qho inorganic compound thiab yog ntsev ntawm phosphoric acid.Nws tuaj yeem tsim cov organic esters nrog ntau yam sib txuas thiab cov no tseem ceeb hauv ntau cov txheej txheem biochemical.Phosphate muaj cov mis empirical PO43-.Nws yog tetrahedral molecule, qhov twg lub hauv paus phosphorus atom yog surrounded los ntawm plaub oxygen atoms.
Hauv cov kab ke lom neeg, phosphate feem ntau pom xws li cov ion dawb (inorganic phosphate) lossis ua ib qho ester tom qab cov tshuaj tiv thaiv nrog cov organic tebchaw (feem ntau hu ua organic phosphates).Inorganic phosphate (feem ntau txhais tau tias yog Pi) yog sib xyaw ntawm HPO42- thiab H2PO4- ntawm lub cev pH.
