Why do not we categorize metal oxides as bases while metal sulphides are considered as salts?

Solution

A salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base, to form the salt of the acid and water.
Metal oxides are bases, so they (generally) react with acids to form salts and water.
$C a O + 2 H C l \to C a C l_{2} + H_{2} O$
In this reaction, the salt is $C a C l_{2}$ (calcium chloride).
Metal sulphides, on the other hand, are salts formed by the reaction of metal bases (such as NaOH) with $H_{2} S$ , which acts as an acid.
$H_{2} S + 2 N a O H \to N a_{2} S + 2 H_{2} O$
