Introduction
In chemistry, pH is a measure of the concentration of hydrogen ions (H+) in a solution. It is a crucial concept in understanding various chemical reactions and processes. The pH scale ranges from 0 to 14, with a pH of 7 being neutral. A pH less than 7 is considered acidic, while a pH greater than 7 is considered basic. In this article, we will explore the relationship between pH and pOH, and discuss the characteristics of a substance with a high [H+].
pH and pOH: What's the Difference?
pH is a measure of the concentration of hydrogen ions (H+) in a solution, while pOH is a measure of the concentration of hydroxide ions (OH-) in a solution. The two are related by the equation:
pH + pOH = 14
This equation shows that as the concentration of hydrogen ions (H+) increases, the concentration of hydroxide ions (OH-) decreases, and vice versa.
Characteristics of a Substance with a High [H+]
A substance with a high [H+] would likely have the following characteristics:
- Low pH: A high [H+] indicates a low pH, which means the substance is acidic.
- Low [OH-]: As the concentration of hydrogen ions (H+) increases, the concentration of hydroxide ions (OH-) decreases.
- High pOH: Since pH + pOH = 14, a high [H+] would result in a high pOH.
Option Analysis
Let's analyze the options:
A. A high [OH-] and a high pOH
This option is incorrect because a high [H+] would result in a low [OH-], not a high [OH-].
B. A low [OH-] and a high pOH
This option is correct because a high [H+] would result in a low [OH-] and a high pOH.
C. A high [OH-] and a low pOH
This option is incorrect because a high [H+] would result in a low [OH-], not a high [OH-].
Conclusion
In conclusion, a substance with a high [H+] would likely have a low pH, a low [OH-], and a high pOH. Understanding the relationship between pH and pOH is crucial in chemistry, and this article has provided a comprehensive guide to help you understand this concept.
Key Takeaways
