Question:
Which one of the following oxides is neutral ?
Which one of the following oxides is neutral ?
Updated On: Jun 14, 2022
- CO
- $SnO_2$
- ZnO
- $SiO_2$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Carbon monoxide is a neutral oxide, all others are amphoteric:
$SnO_2 + 4HCI \longrightarrow SnCI_4 + 2H_2O$
$ZnO + 2HCI \longrightarrow ZnCI_2 + H_2O$
$SiO_2 + 2NaOH \longrightarrow Na_2SiO_3 + H_2O$
$SnO_2$ and ZnO also react with NaOH. $SiO_2$ is also attacked by $H_3PO_4$.
$SnO_2 + 4HCI \longrightarrow SnCI_4 + 2H_2O$
$ZnO + 2HCI \longrightarrow ZnCI_2 + H_2O$
$SiO_2 + 2NaOH \longrightarrow Na_2SiO_3 + H_2O$
$SnO_2$ and ZnO also react with NaOH. $SiO_2$ is also attacked by $H_3PO_4$.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
