Question

fan and medal!!!!!
The [H+] concentration of an acetic acid solution is 1 x 10^(-4) mol/L.

Calculate the pH of the solution?

Answer 1

The pH is calculated by finding the negative log of the H+ concentration:

\[pH=-\log([H+])\]
Using this equation, your pH is...?

Answer 2

4? @matt101

Answer 3

That's right!

Answer 4

It's a moderately acidic solution, which is exactly what you'd expect from acetic acid, which is a weak acid.
