Question

What is the concentration of hydronium ions in a substance that has a pH of 6.2?

Answer 1

The concentration of hydronium ions (\(\sf H_3O^+\)or simply \(\sf H^+\)) is defined as the pH.

\(\sf \large pH = - log [H_3O^+]\)

to invert this (calculating H3O+ with pH), use the following formula:

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

Answer 2

\[1\times10^{(-6.2)} = 6.31\times10^{-7} H30\]

Answer 3

@kametri7 the answer is for the asker to figure out...

Answer 4

thomaster how do you get the 10 in the 2nd formula?

Answer 5

the opposite of a = log(x) is x= 10^(a)

Answer 6

alright thank you
