Question

1. What is the difference between moleule and Covalent bond if there's not a difference then Give similarities between them ?

2. How CO2 gas is an acidic ?

Please give in detailed solution....

Answer 1

Molecular bonds or covalent bonds are exactly the same.



A solution of carbon dioxide is slightly acidic but carbon dioxide by itself is not an acid. The reason why it is slightly acidic in solutions is because it can (no matter how weak) establish an equilibrium with water to give hydrogen ions:
CO2(g)+H2O(l)⇌H+(aq)+HCO−3(aq)CO2(g)+H2O(l)⇌H+(aq)+HCO3−(aq)
