Question

hydroxyl ion concentration is 10^-3 M what is proton concentration? explain please?

Answer 1

that's why i hate chemistry, too much bullpellet for a simple division

Answer 2

ikr, so do you know how to do it?

Answer 3

or explain?

Answer 4

If you measure the pH of a given solution, concentration of H+ is calculated applying the definition:

pH = - log [H+] (logarithm in base 10)

so, [H+] = 10^-pH

For example, if pH= 4.6 then the [H+] = 10^-4.6 = 2.5 x 10^-5 mol/L

Answer 5

i have an idea...
how many protons and neutrons are in the ion ?

Answer 6

im like completely lost on this, so you're gonna have to please please explain it to me as if you're explaining it to a 5th grader

Answer 7

@saygilim do you know that the hydrogen ion conc is equal to the proton conc?
so basically we have pOH which is potence hydroxyl.
pOH= -log[OH^-] So like abood2013 said for pH in the same manner pOH is found.
so pOH comes out to be 3.
now pH + pOH= 14
so pH+ 3=14
pH=11
pH= -log[H^+]
so [h^+]= 10^-11]
so the conc of proton is 10^-11.
hope you got it.

Answer 8

\([H^+]\) is called the hydronium ion (more correctly written as \([H_3O^+]\)) not the proton concentration because \(H^+\) doesn't exist on it's own. In solution it's present as \(H_3O^+\).

Answer 9

@aaronq so whatever i have written is correct?

Answer 10

Yes, what you wrote is correct. It's only the terminology used ("proton concentration") that is incorrect.

Answer 11

ohh...cool den:)
