How many oxides among the following are basic in nature? aligned & As ₂ O ₃, Na ₂ O , MgO , Mn ₂ O ₃, CaO , ZnO , N ₂ O , & N ₂ O ₅ aligned

Options

  1. A4
  2. B5
  3. C3
  4. D6

Correct answer

A. 4

Step-by-step solution

Metal + Oxygen Metal oxide Metal oxides are basic in nature. Therefore, Na ₂ O , MgO and CaO are basic in nature. ZnO is amphoteric in nature i.e., it can react with both acids as well as alkalis to form salt. ZnO +2 HCl ZnCl ₂+ H ₂ O Basic oxides are Na ₂ O , MgO , CaO , ZnO .
