classify the following reactions as acidic anhydride or basic anhydride.

Solution

Acidic anhydrides :

N2O5 + H2O   ------------> 2 HNO3

SO3 +   H2O    --------------> H2SO4

P4O10 + 6 H2O   -------------> 4 H3PO4

Basic anhydrides:

MgO +   H2O   ----------------> Mg(OH)2

Li2O + H2O   -------------> 2 LiOH

ZnO +   H2O    --------------> Zn(OH)2

Explanation :

if compound is added to water , it produce acid , then it is called acidic anhydride.

if compound is added to water , it produce base , then it is called as basic anhydride
