Tsis muaj cov ntaub ntawv pom rau qhov sib tshooj chemical nophenomenon
Cov kab zauv no tsis muaj cov ntaub ntawv tshwj xeeb hais txog qhov tshwm sim.
Hauv qhov no, koj tsuas yog xav kom soj ntsuam seb cov khoom puas muaj nuj nqi Cr (OH) 3, tshwm sim thaum kawg los ntawm cov tshuaj tiv thaiv.
Lossis yog ib yam hauv qab no cov tshuaj txhaum cai KCrO2 (Cov Paab Nrov Chromate (III)), ploj mus
Tshaj Tshawb Nrhiav nrog kev pab ntawm Google Search Engine
Peb tau koom tes nrog Google tsim kev ua tiav nrog kev tshawb pom nrog cov txiaj ntsig nrog cov ncauj lus tsis yog tsuas
Nyem rau qhov no kom paub cov ntaub ntawv ntau ntxiv txog kab zauv noQhov sib luag nrog H2O li reactant
dej
Sib nrug nrog HCl ua reactant
hydrogen tshuaj dawb
Qhov sib npaug nrog KCrO2 li reactant
Qab Zib potassium Chromate (III)
H2O + HCl + KCrO2 => KCl + Cr (OH)3 3Br2 + 8KOH + 2KCrO2 => 4H2O + 2K2CRO4 + 6NaBr 3T2 + 8KOH + 2KCrO2 => 4H2O + 6KCl + 2K2CRO4 Saib txhua qhov sib npaug nrog KCrO2 raws li reactant
Qhov sib npaug nrog KCrO2 ua cov khoom
Qab Zib potassium Chromate (III)
2KOH + Cr2O3 => H2O + 2KCrO2 KOH + Cr (OH)3 => 2H2O + KCrO2 Saib txhua qhov sib npaug nrog KCrO2 ua cov khoom
Qhov sib npaug nrog KCrO2 ua cov khoom
Qab Zib potassium Chromate (III)
2KOH + Cr2O3 => H2O + 2KCrO2 KOH + Cr (OH)3 => 2H2O + KCrO2 Saib txhua qhov sib npaug nrog KCrO2 ua cov khoom
