Question

Bài tập: Cho NaOH, Mg(OH)2, Ba(OH)2, Al(OH)3, Cu(OH)2. Bazơ nào a) Tác dụng SO2, CO2, viết PTHH? b) Tác dụng HNO3, HCl, viết PTHH? c) Bị nhiệt phân hủy, viết PTHH?

Answer 1

a)

$2NaOH + CO_2\to Na_2CO_3 + H_2O$
$2NaOH + SO_2 \to Na_2SO_3 + H_2O$
$Ba(OH)_2 + CO_2 \to BaCO_3 + H_2O$
$Ba(OH)_2 + SO_2 \to BaSO_3 + H_2O$

b)

$NaOH + HCl \to NaCl + H_2O$
$NaOH + HNO_3 \to NaNO_3  + H_2O$
$Mg(OH)_2 + 2HCl \to MgCl_2 + 2H_2O$

$Mg(OH)_2 + 2HNO_3 \to Mg(NO_3)_2 + 2H_2O$

$Ba(OH)_2 + 2HCl \to BaCl_2 + 2H_2O$

$Ba(OH)_2 + 2HNO_3 \to Ba(NO_3)_2 + 2H_2O$

$Cu(OH)_2 + 2HCl \to CuCl_2 + 2H_2O$

$Cu(OH)_2 + 2HNO_3 \to Cu(NO_3)_2 + 2H_2O$

$Al(OH)_3 + 3HCl \to AlCl_3 + 6H_2O$

$Al(OH)_3 + 3HNO_3 \to Al(NO_3)_3 + 6H_2O$

c)

$Mg(OH)_2 \xrightarrow{t^o} MgO + H_2O$
$2Al(OH)_3 \xrightarrow{t^o} Al_2O_3 + 3H_2O$
$Cu(OH)_2 \xrightarrow{t^o} CuO + H_2O$
