Question:
Identify the correct order of acidic strength of $CO_2, CuO, CaO, H_2O$
Identify the correct order of acidic strength of $CO_2, CuO, CaO, H_2O$
Updated On: Jun 14, 2022
- $CaO < CuO < H20 < CO_2$
- $H_2O < CuO < CaO < CO_2$
- $CaO < H_2O < CuO < CO_2$
- $H_2O < CO_2 < CaO < CuO$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$CO_2$ is acidic oxide, $H_2O$ is neutral, CaO is strongly basic and CuO is weakly basic. Therefore, order of acid strength is : $ \, \, \, \, \, \, CaO < CuO < H_2O < CO_2$

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
