Concept explainers
Interpretation:
The pH of a 0.256 M NaOH solution needs to be calculated.
Concept Introduction:
The acidity of a solution is expressed in terms of its pH which is essentially the measure of the hydrogen ion (H+) concentration of that solution. Mathematically,
If the pH is below 7 the solution is termed as acidic, if greater than 7 the solution is basic. A neutral solution will have a pH = 7
The pH and pOH are related by the following equation:
Where:
Answer to Problem 8E
13.4.
Explanation of Solution
The concentration of NaOH = 0.256 M
Since NaOH is a strong base, the OH- concentration is 0.256 M
The pOH of the solution can be calculated as follows:
The pH of the solution can be calculated as follows:
Thus, the pH of 0.256 M NaOH solution is 13.4.
