Concept explainers
(a)
Interpretation:
The stronger acid between HCl and H2O should be determined.
Concept Introduction :
For a strong acid, equilibrium lies far to the right. That means almost all the acid molecules are dissociated at the equilibrium and solution contains the free ions. For a weak acid, the equilibrium lies far to the left. That means most of the acid molecules still present as acid molecules and dissociated to a very small extent.
(b)
Interpretation:
The stronger acid between H2O and HNO2 should be determined.
