Question

Выбрать вещества, с которыми реагирует Al(OH)3 а) CO2 б)NaOH в)H2SO4

Answer 1

Ответ:б) NaOH

Объяснение:

Answer 2

Al(OH)3, also known as aluminum hydroxide, can react with the following substances:

а) CO2 (carbon dioxide): When aluminum hydroxide reacts with carbon dioxide, it forms aluminum carbonate (Al2(CO3)3). The reaction is as follows:

2 Al(OH)3 + 3 CO2 → Al2(CO3)3 + 3 H2O

б) NaOH (sodium hydroxide): Aluminum hydroxide reacts with sodium hydroxide to form sodium aluminate and water. The reaction is as follows:

Al(OH)3 + 3 NaOH → NaAl(OH)4

в) H2SO4 (sulfuric acid): Aluminum hydroxide reacts with sulfuric acid to form aluminum sulfate and water. The reaction is as follows:

2 Al(OH)3 + 3 H2SO4 → Al2(SO4)3 + 6 H2O
