Branch's Alum Battery

[Branch Gordon]

Hey John K-

Yeah I thought about that previously remember. I posted a vid of me adding 1.5ml of distilled water in order the raise the PH. John B however commented that if I went the "water battery" route I would end up with a really weak battery. He has been saying this whole time that I need to add more acid.

That is the source of my confusion.

Branch, I don't have the answer but maybe something to think about if you think you need to raise the pH.

What is the pH of the following 3 chemicals?

• Alum
• SO4
• Distilled water

What do you think you need to add to the mix to raise the pH?

I decided to start my own thread here so I can keep my progress more organized and have a better record. Hopefully JB will see this...

I tested my PH tonight with my new paper test strips. Results in video. Any suggestions anyone?
