Concept explainers
(a)
Interpretation:
The given acids are to be arranged in the order of increasing acid strength.
Concept introduction:
The strength of acids and bases can be determined on the basis of their dissociation reactions and their dissociation constants. Those acids or bases which dissociate almost completely are strong acids or strong bases and those which dissociate to smaller extents are weak or moderately weak acids or bases.
(b)
Interpretation:
The given acids are to be arranged in the order of increasing base strength of conjugate bases.
Concept introduction:
A conjugate base is formed by removal of a proton. The strength of an acid depends upon the stability of conjugate base. Stable is the conjugate base higher is the acidic strength of the acid.
