Question

The pH of a vinegar solution is 4.15. What is the H3O+ concentration of the solution?

Answer 1

use: \(pH=-log[H_3O^+]\)

Answer 2

How exactly do I do that? What is -log?

Answer 3

it's the logarithmic function. to find \([H_3O^+]\) from there you need to take the inverse:

\([H_3O^+] = 10^{-pH}\)

Answer 4

so 10^-4.15?

Answer 5

yep

Answer 6

Thank you sir

Answer 7

no problem
