If it does have a pH, I mean. Though I don't see why it shouldn't have it.
I got interested into this when I learned that the electric charges for antimatter particles are the opposite of those for matter particles (i.e.: positively charged positrons orbiting around negatively charged antiprotons).
So I was thinking... If I mixed anti-hydrogen chloride with anti-sodium hydroxide to make anti-salt, it would be the anti-HCl that would be donating negative charged ions, and the anti-NaOH that would be providing the positive charges.
Does that mean that the pH of a matter substance and its antimatter counterpart are reversed in relation to each other? Would anti-LSD be a base instead of an acid?
Edit: I understand that getting matter in contact with antimatter will cause anihilation. I know that trying to neutralize an antimatter acid with a matter base
would be great fun would never work. While asking this question I had a "bizarro" anti-matter world in mind. I was thinking, for example, how some anti-lemmon battery would work, since the anti-ions would be going in different ways when compared to a lemon battery in our matter world.
