Acidic oxide and anhydride are both oxides of non-metals, but they differ in their chemical properties and how they react with water.
A

n acidic oxide is an oxide that reacts with water to form an acid. These oxides are usually non-metal oxides, which react with water to produce an acidic solution. Examples of acidic oxides include sulfur dioxide (SO2) and nitrogen dioxide (NO2).
For example, sulfur dioxide (SO2) reacts with water to form sulfurous acid (H2SO3):
SO2 + H2O → H2SO3
Nitrogen dioxide (NO2) reacts with water to form nitric acid (HNO3):
NO2 + H2O → HNO3
An anhydride, on the other hand, is an oxide that reacts with water to form an acid or a base, depending on the type of anhydride. Anhydrides are usually formed from the dehydration of acids or their salts. Examples of anhydrides include acetic anhydride (C4H6O3) and phosphorus pentoxide (P2O5).
For example, acetic anhydride (C4H6O3) reacts with water to form acetic acid (CH3COOH):
C4H6O3 + H2O → 2CH3COOH
Phosphorus pentoxide (P2O5) reacts with water to form phosphoric acid (H3PO4):
P2O5 + 3H2O → 2H3PO4
In summary, the key difference between acidic oxides and anhydrides is that acidic oxides react with water to form acids, whereas anhydrides can react with water to form either an acid or a base, depending on the type of anhydride.
