FeCl3+NaOH--->Fe(OH)3+NaCl
.................................................

 

[trannrinn]

3HNO3 +Fe(OH)3------->3H2O+Fe(NO3)3 .

[trannrinn]

Al(OH)3 +NaOH------->2H2O+NaAlO2 .

 

[nom1]

H2O + Na2O -> 2NaOH

NaAlO2+HCl--->NaCl+AlCl3+H2O
....................................................

 

[nom1]

NaCl -dpnc-> Na + Cl2
...................................

 

[trannrinn]

Cl2 + 2NaOH----> NaCl + NaClO + H2O .

 

[toiyeu9a3]

CuSO4+BaCl2--->BaSO4+CuCl2
..................................................

 

[nom1]

BaSO4 + AgNO3 -> Ba(NO3)2 + AgSO4
................................................. ít tan xem như ko tan

 

[phankyanhls2000]

BaSO4 + AgNO3 -> Ba(NO3)2 + AgSO4
................................................. ít tan xem như ko tan

Hai muối pu phải tan và sp phải có 1 chất kt.
BaSO4 không tan,pt sai rồi nhe.Và Ag2SO4 chứ đâu phải AgSO4

 

[nom1]

quên mất BaSO4 rồi.. haiz thiệt là
CuCl2 + AgNO3 -> Cu(NO3)2 + AgCl
.............................................

 

[phankyanhls2000]

Cu(NO3)2+NaOH--->Cu(OH)2+NaNO3
...........................................................

 

[nom1]

Cu(OH)2 -to-> CuO + H2O
