Hey, I need to figure out how to calculate the concentration of hydronium ions using given pH levels. Can you explain to me how?

Ex. Find the concentration of hydronium ions with the pH level is 2.3.

Thanks a bundle. Slight Smile

pH= -log[H+].
[H+]= -antilog(pH).
      = -antilog(2.3)
Find the antilog of 2.3 in antilog table. you will get the answer

Yeah! That's easy!

Basically the concentration of hydronium ions is 10^(-n) per liter of water

n is the pH

so it's 10^(-2.3) per liter
ten to the power of negative 2.3

sorry I don't have a calculator to simplify. You can do it yourself
