Concept explainers
(a)
Interpretation:
For solution of same concentration as acid strength increases, the change in the [H+] has to be described.
Concept Introduction :
For an acidic solution, the pH value is less than 7 due to large concentration of hydrogen ion/s. It is less than for the basic solution having less concentration of hydrogen ions.
(b)
Interpretation:
For solution of same concentration, as acid strength increases, the change in pH has to be described.
Concept Introduction :
For an acidic solution, the pH value is less than 7 due to large concentration of hydrogen ion/s. It is less than for the basic solution having less concentration of hydrogen ions.
(c)
Interpretation:
For solution of same concentration, as acid strength increases the change in [OH-] has to be described.
Concept Introduction :
For an acidic solution, the pH value is less than 7 due to large concentration of hydrogen ion/s. It is less than for the basic solution having less concentration of hydrogen ions.
(d)
Interpretation:
For solution of same concentration, as acid strength increases the change in pOH has to be described.
Concept Introduction :
For an acidic solution, the pH value is less than 7 due to large concentration of hydrogen ion/s. It is less than for the basic solution having less concentration of hydrogen ions.
(e)
Interpretation:
For solution of same concentration, as acid strength increases the change in Ka has to be described.
