Question

Al2O3+HNO3= Al2O3+KOH= Al(OH)3+H2SO4= Al(OH)3+Na(OH)=

Answer 1

Al₂O₃+6HNO₃=2Al(NO₃)₃+3H₂O
2KOH+Al₂О₃=2KAlО₂+Н₂О
2Al(OH)3+3H2SO4=Al2(SO4)3+6H2O
Al(OH)3+Na(OH)=NaAlO2+2H2O

Answer 2

Al2O3 + HNO3 = Al(NO3)3 + H2O Al2O3 + KOH = KAl(OH)4 Al(OH)3 + H2SO4 = Al2(SO4)3 + 3H2O Al(OH)3 + Na(OH) = NaAl(OH)4
