Most acidic Least acidic Ni2Os MnO Cu2O The correct ranking cannot be determined
Solution
metallic oxides are basic in nature
nonmetallic oxides are acidic in nature
Sc, Ti, V, Cr, Mn, Fe,Co, Ni , Cu, Zn are 4th period elements.In a period oxide acidic nature
increases from left to right.
V2O3 is most acidic
ZnO is least acidic
V2O3 >MnO>Ni2O3> Cu2O> ZnO
