The total number of acidic oxides from the following list is: NO , N 2 O , B 2 O 3 , N 2 O 5 , CO , SO 3 , P 4 O 10

Options

  1. A5
  2. B4
  3. C3
  4. D6

Correct answer

B. 4

Step-by-step solution

Based on their acid-base characteristics oxides are classified as acidic or basic. An oxide that combines with water to give an acid is termed as an acidic oxide. The oxide that gives a base in water is known as a basic oxide. P 4 O 10 ,   B 2 O 3 ,   N 2 O 5 ,   SO 3 are acidic oxides. NO ,   N 2 O ,   CO are neutral oxides.
