Al(OH)3+ ? =AlCl3 + ? Al2O3+ ? =NaAlO2 + ? Al(OH)3 + ? = NaAlO2

Question

Al(OH)3+ ? =AlCl3 + ?
Al2O3+ ? =NaAlO2 + ?
Al(OH)3 + ? = NaAlO2

Answer 1

Al(OH)3 + 3HCl = AlCl3 + 3H2O

Al2O3 + 2NaOH = 2NaAlO2 + H2O

Al(OH)3 + NaOH = NaAlO2 + 2H2O

Answer 2

Al(OH)3 + 3HCl -> AlCl3+ 3H2O
Al2O3 + 2NaCO3 (тв.) --900-200(град. С)--> 2NaAlO2 + CO2
Al(OH)3 + NaOH(тв.) --t--> NaAlO2 + 2H2O
