Question

Viết PTHH xảy ra giữa Cu(OH)2, NaOH, Ba(OH)2, Fe(OH)3,Zn(OH)2, Mg(OH)2, Al(OH)3, KOH, Fe(OH)2 với axit HCl, H2SO4. 

Answer 1

- H₂SO₄:

\(Cu\left(OH\right)_2+H_2SO_4\rightarrow CuSO_4+2H_2O\\ 2NaOH+H_2SO_4\rightarrow Na_2SO_4+2H_2O\\ Ba\left(OH\right)_2+H_2SO_4\rightarrow BaSO_4\downarrow+2H_2O\\ 2Fe\left(OH\right)_3+3H_2SO_4\rightarrow Fe_2\left(SO_4\right)_3+3H_2O\\ Zn\left(OH\right)_2+H_2SO_4\rightarrow ZnSO_4+2H_2O\)

\(Mg\left(OH\right)_2+H_2SO_4\rightarrow MgSO_4+2H_2O\\ 2Al\left(OH\right)_3+3H_2SO_4\rightarrow Al_2\left(SO_4\right)_3+3H_2O\\ 2KOH+H_2SO_4\rightarrow K_2SO_4+2H_2O\\ Fe\left(OH\right)_2+H_2SO_4\rightarrow FeSO_4+2H_2O\)

- HCl:

\(Cu\left(OH\right)_2+2HCl\rightarrow CuCl_2+2H_2O\\ NaOH+HCl\rightarrow NaCl+H_2O\\ Ba\left(OH\right)_2+2HCl\rightarrow BaCl_2+2H_2O\\ 2Fe\left(OH\right)_3+6HCl\rightarrow2FeCl_3+3H_2O\\ Zn\left(OH\right)_2+2HCl\rightarrow ZnCl_2+2H_2O\\ Mg\left(OH\right)_2+2HCl\rightarrow MgCl_2+2H_2O\\ 2Al\left(OH\right)_3+6HCl\rightarrow2AlCl_3+3H_2O\\ KOH+HCl\rightarrow KCl+H_2O\\ Fe\left(OH\right)_2+2HCl\rightarrow FeCl_2+2H_2O\)
