Question

Be,BeO и Be(OH)2 примеры реакций илюстрирующие амфотерный характер

Answer 1

Be + 2HCl = BeCl2 + H2

Be + 2NaOH = Na2BeO2 + H2

Be + 2NaOH + 2H2O = Na2[Be(OH)4] + H2

BeO + 2HCl = BeCl2 + H2O

BeO + 2NaOH = Na2BeO2 + H2O

BeO + 2NaOH + H2O = Na2[Be(OH)4]

Be(OH)2 + 2HCl = BeCl2 + 2H2O

Be(OH)2 + 2NaOH = Na2BeO2 + 2H2O

Be(OH)2 + 2NaOH = Na2[Be(OH)4]
