    Ph Relation
AI Thread Summary
The relationship between pH and hydrogen ion concentration is defined by the equation pH = -log[H+]. This means that pH is the negative logarithm of the hydrogen ion concentration. The discussion confirms that this relationship is straightforward and not complicated. For further understanding, one can refer to the definitions and scales of pH. The initial confusion is clarified, affirming the accuracy of the formula.

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.
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
Thread 'How to find the pH of a galvanic cell (MIT OCW problem set)'
This is the final problem in this problem set from MIT OCW. Here is what I did to try to solve it The table cited in the problem is below We can easily spot the two redox couples that are in the electrochemical cell we are given. The hydrogen-based electrode has standard potential zero, and the silver-based electrode has standard potential 0.22. Thus, the hydrogen electrode, with the lower potential, is the reducing agent (ie, it is where oxidation happens) and is the anode. Electrons...
