Which Substance Has the Lowest Hydrogen Ion Concentration?

AI Thread Summary
The discussion focuses on identifying which substance has the lowest hydrogen ion concentration among 0.1 M HCl, 0.1 M NaOH, 0.1 M H2SO4, and pure water. Participants suggest calculating the pH based on the dissociation of each compound's ions. It is emphasized that the substance with the highest dissociation will yield the most hydrogen ions. The conversation indicates that understanding acids and bases is crucial for solving this problem. Ultimately, the lowest hydrogen ion concentration is found in pure water.

I am trying to find the lowest concentration of hydrogen ions out of the following:

0.1 M HCl
0.1 M NaOH
0.1 M H2SO4
pure water

I am having a hard time with the book and this...Thanks

Have you tried writing down the Ionic components of each of the three compounds you list? then calculate the pH of each solution from the molar quantities of each ion present

Umm, not to be dumb or anything, but how does one go about that:(
 
Might I suggest http://www.google.com/" to get you started

The highest concentration of hydrogen ions comes from the substance which has the most hydrogen ions to dissociate. Notice that for the solutes, each choice is 0.1 M, except for the distilled water choice. Now, for each mole of solute, which one gives the most hydrogen ions?

You need to be studying acids and bases in your chemistry course (at least "Introductory") in order to know how to answer.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

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...
