What Is The PH Of A Solution With A $2.20 \times 10^{-8} M$ Hydroxide Ion Concentration?A. 0.342 B. 6.00 C. 6.34 D. 7.66
Understanding pH and pOH
pH is a measure of the concentration of hydrogen ions in a solution, while pOH is a measure of the concentration of hydroxide ions. The two are related by the equation: pH + pOH = 14. This equation is a fundamental concept in chemistry and is used to determine the pH of a solution when the pOH is known.
Calculating pOH
To calculate the pOH of a solution, we use the formula: pOH = -log[OH-], where [OH-] is the concentration of hydroxide ions in moles per liter (M). In this case, we are given a hydroxide ion concentration of $2.20 \times 10^{-8} M$.
Applying the Formula
Using the formula pOH = -log[OH-], we can plug in the given concentration of hydroxide ions to calculate the pOH.
pOH = -log($2.20 \times 10^{-8} M$)
Using a Calculator
To solve this equation, we can use a calculator to find the logarithm of the concentration of hydroxide ions.
pOH = -log($2.20 \times 10^{-8} M$) ≈ 7.66
Understanding the pH
Now that we have calculated the pOH, we can use the equation pH + pOH = 14 to find the pH of the solution.
Calculating the pH
pH + 7.66 = 14
Solving for pH
pH = 14 - 7.66
Calculating the pH Value
pH ≈ 6.34
Conclusion
Therefore, the pH of a solution with a $2.20 \times 10^{-8} M$ hydroxide ion concentration is approximately 6.34.
Answer Choice
The correct answer is C. 6.34.
Additional Information
It's worth noting that the pH of a solution can be affected by many factors, including the concentration of hydrogen ions, the presence of other ions, and the temperature of the solution. In this case, we have assumed that the solution is at a standard temperature (usually 25°C) and that there are no other ions present that could affect the pH.
Final Thoughts
In conclusion, the pH of a solution with a $2.20 \times 10^{-8} M$ hydroxide ion concentration is approximately 6.34. This is a fundamental concept in chemistry and is used to determine the pH of a solution when the pOH is known.
