Solution

$S O_{3}, C l_{2} O_{7}, N_{2} O_{5}, G e O_{2} A c i d i c$
$C r_{2} O_{3} A m p h o t e r i c$
$K_{2} O, B a O B a s i c$
$C O, N e u t r a l$
Reactions :
$S O_{3} + 2 N a O H ⟶ N a_{2} S O_{4} + H_{2} O$
$C l_{2} O_{7} + 2 N a O H ⟶ 2 N a C l O_{4} + H_{2} O$
$N_{2} O_{5} + 2 N a O H ⟶ 2 N a C l O_{4} + H_{2} O$
$C O + N a O H ⟶ N o r e a c t i o n$
$K_{2} O + N a O H ⟶ N o r e a c t i o n b u t K_{2} O + H_{2} O ⟶ 2 K O H$
$B a O + N a O H ⟶ N o r e a c t i o n b u t B a O + H_{2} O ⟶ B a (O H)_{2}$
$C r_{2} O_{3} + 2 N a O H + 3 H_{2} O ⟶ 2 N a [C r (O H)_{4}]$
$G e O_{2} + 2 N a O H + 3 H_{2} O ⟶ N a_{2} G e O_{3} + H_{2} O$
