(a)
Interpretation: The hydrogen ion concentration of a solution with a pH value of 4.00 needs to be calculated.
Concept Introduction: The pH of the solution is calculated from hydrogen ion concentration as follows:
The above relation can be rearranged to calculate the hydrogen ion concentration.
(a)
Explanation of Solution
The pH of the solution is given 4.00. It is related to hydrogen ion concentration as follows:
Thus, hydrogen ion concentration can be calculated from pH value as follows:
Substitute the value,
Thus, the hydrogen ion concentration of the solution is
(b)
