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

A $5$
B $4$
C $3$
D $6$

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.
