Welcome to Scratch Chemist.
It wasn't until my son started taking chemistry in high school and asked me about pH that we realized much of what I had learned about pH's "acid and alkaline" was out of date, or just plain wrong.
Going online looking for pH charts didn't result in anything useful. Not wanting to give up I decided to learn everything I could and to create a pH reference sheet from scratch.
The result is the "Scratch Chemist's pH Scale" which you pH values across common foods we eat, the human by-products we create, the pool water we swim in, the chemicals we clean with, and the soil we grow food in.
If you would like a copy of the "Scratch Chemist's pH Scale" please use either the free portable network graphic (PNG) or the $1 portable document format (PDF) version.
You are welcome to use it as you wish, I just ask that you keep the QR and URL code for those that want to find the latest version. Educators are encouraged to give copies to their students.
Thank you for your support and distribution of the Scratch Chemist pH Scale.

5/2018 - version 1.44 Correction for Subscript and Superscript of H2O and CO2. Left H+ and OH- without superscripting to keep it readable. Kept exponents as E10-x instead of superscripting to match student calculators.
1.41
Correction for pH0 and pH14 to list H+ and OH- at 1mol/L (and not .1mol/L)
