Question

Otrzymywanie wodorotlenków NaOH, KOH, Ca(OH)2, Cu(OH)2, Al(OH)3

Answer 1

2Na+2H2O--->2NaOH+H2

Na2O+H2O--->2NaOH

NaH+H2O--->NaOH+H2

2K+2H2O--->2KOH+H2

K2O+H2O--->2KOH

KH+H2O--->KOH+H2

Ca+2H2O--->Ca(OH)2+H2

CaO+H2O--->Ca(OH)2

CaH2+2H2O--->Ca(OH)2+2H2

CuCl2+2NaOH--->Cu(OH)2↓+2NaCl

Al(NO3)3+3KOH--->Al(OH)3↓+3KNO3
