(a)
Interpretation:
The acidic anhydride of H2SO4 should be determined.
Concept introduction -
Anhydrides implies “without water”. Acid anhydrides are compound when reacts with water forms respective acid.
Acid anhydride + water → Acid
For example: CO2 is an acid anhydride when reaction with water H2O forms H2CO3.
To find the acid anhydrides from their acid, water need to be removed.
(b)
Interpretation:
The acidic anhydride of H2SO3 should be determined.
