Discussion Overview

The discussion centers on the relationship between pH and the concentration of hydrogen ions ([H+]), exploring the mathematical definition of pH and its implications.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant questions how pH relates to [H+], suggesting that the relationship might be more complex than they initially thought.
  • Another participant confirms that the relationship is defined by the equation pH = -log[H+], agreeing with the initial participant's understanding.
  • A third participant expresses surprise that the answer is not more complicated, indicating an expectation of a more intricate explanation.
  • A fourth participant suggests that the definition of pH and the pH scale provide sufficient detail, implying that the basic relationship does not require further complexity.

Areas of Agreement / Disagreement

There is agreement on the mathematical relationship between pH and [H+], but some participants express curiosity about the potential for a more complex explanation, indicating a lack of consensus on the depth of understanding required.

Hi my question is How does the pH relate to the concentration of Hydrogen ions?

what I think is The relationship between the pH and the concentration of Hydrogen ions is that the -log of the hydrogen ion concentration is equal to the pH, but this doesn't seem right at all.

can someone please help me out?:confused:
 
Physics news on Phys.org
The pH is pH = -\log[H^{+}]. So you are correct.
 
I thought there would be a more complicated answer
 
Nope. See pH definition and pH scale for more details - but they won't change what courtrigrad have already wrote.
