Question

What kind of oxide is ZnO . Support your answer by writing two chemical reactions

Answer 1

Zinc oxide is an amphoteric oxide. It is nearly insoluble in water, but it will dissolve in most acids, such as hydrochloric acid: ZnO + 2 HCl → ZnCl2 + H2O.

Answer 2

Q. What kind of oxide is ZnO . Support your answer by writing two chemical               reactions  ?                                                                                                                                              

ans . ZINC OXIDE IS AN AMPHOTERIC OXIDE WHICH DOESNOT DISSOLVE IN WATER BUT REACTS WITH ACIDS .

FOR EXAMPLE --

  Zinc oxide is amphoteric because it reacts with both acids and bases to form salts.

ZnO   +   2HCl   →   ZnCl2       +      H2O

                      [ Zinc chloride ]

2NaOH + ZnO  →  Na2ZnO2      +      H2O

                    [ Sodium zincate]
