Having same measure, 0.001 M strong acid and 0.001 weak acid
« on: November 11, 2013, 05:13:54 PM »
If you have a measure of the same, like 0.001 M of a strong acid and 0.001 M of a weak acid,  is it measured the same ?

Or it depends on the identity of the strong and weak acid, or the pH of the weak acid solution is higher?

I will take a guess.. I think it depends on the identity of the strong and weak acid?  Not sure.

Nvm, I think the answer is  the pH of the weak acid solution is higher.   At the same molarity, a strong acid will have a lower pH than a weak acid as I saw somewhere!

Measure of what? Concentration of the acid? It is the same. pH? Conductivity? Absorbance? Osmolality? Buffering capacity? All different.

As you see question as posted is rather ambiguous.

We all have trouble with his questions. All of the students do have trouble, hah.  I will google about strong acid and weak acid having the same molarity and see what I can learn.

I got this one right on the quiz. I only got one wrong out of 32.  I am glad you guys didn't give me the answers, I had to google and read, read.. which is good.
