Al reacts with NaOH, NaAlO2 reacts with HCl, and Al reacts with NaO. Write their chemical reaction equations
2Al+2NaOH+2H2O==2NaAlO2+3H2(g)
NaAlo2+Hcl+H2o=Nacl+Al (oH)3 at 1:1 When NaAlo2+4Hcl=Nacl+3Alcl3+2H2o is between 1:4 and 1:4, there are both aluminum hydroxide and aluminum chloride
NaO? Never seen it.
X+HCl→Y+NaOH→Z X. Where X represents the substance A.AgNO3 B.Fe2O3 Detailed explanation X+HCl→Y+NaOH→Z X. Where X represents the substance A.AgNO3 B.Fe2O3 Ask for detailed explanation
Select B.Fe2O3
Because AgCl produced by reaction in A can not react with NaOH.
In B, Fe2O3+HCl→FeCl3+H2O
FeCl3+ NaOH→Fe (OH)3+ NaCl
Fe (OH)3 Fe 2O 3.
