Solution

The correct options are
B
By reacting basic oxides and

C
By precipitation from heavy metal carbonates

The metallic carbonates and bicarbonates are prepared:
By passing $C O_{2}$ through an alkali.
$2 N a O H + C O_{2} \to N a_{2} C O_{3} ↓ + H_{2} O$
$N a C O_{3} + C O_{2} + H_{2} O \to 2 N a H C O_{3}$
Excess(Soluble)
Heavy metal carbonates are precipitated from the salt solutions with washing soda.
$N a_{2} C O_{3} + B a C l_{2} \to B a C O_{3} ↓ + 2 N a C l$
By reaching basic oxides and $C O_{2}$ .
$K_{2} O + C O_{2} \to K_{2} C O_{3}$

$N a_{2} O + C O_{2} \to N a_{2} C O_{3}$
