this makes absolutley no sense I plug all this into my calculator but I get different results.
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH.

[H3O+] = 10-pH or [H3O+] = antilog (- pH)

Example: What is the hydronium ion concentration in a solution that has a pH of 8.34?


8.34 = - log [H3O+]
- 8.34 = log [H3O+]
[H3O+] = 10-8.34 = 4.57 x 10-9 M

On a calculator, calculate 10-8.34, or "inverse" log ( - 8.34).

Your calculations baffle me.

On my calculator,
INV log(- 8.34) is 4.57E-9 M. So we got the same answer.

You need to figure out what you are doing wrong with your calc.

  1. I don’t get it, how does a ph of 8.34 have anything to do with the number 4.57?? Where are you pulling that from? Literally, tell me the exact buttons to press in the exact order on my calculator, cause this h3o+ thing is actually pissing me off cause this math isn’t checking out. This is why I hate algebra lmao.
