Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. It's 100% free, no registration required.

Bit stuck on working this out - or if it is even possible.

I have a reservoir of solution (water/plant feed/dead flies) that is pH 6 and I want to get it to pH 6.25. Here is the information I have:

  • Size of reservoir: 50 liters
  • pH of reservoir: 6
  • Required pH: 6.25
  • Alkali/Base Stuff: Potassium Hydroxide at 50% Strength

Is there any way I can work this out to say, 15 or 20%?

Many Thanks

Hi James, welcome to Physics Stack Exchange! Sorry to disappoint on your first question, but this is about pure chemistry, not physics, which makes it off topic for this site. –  David Z Sep 26 '11 at 20:15

Note that there is a Chemistry proposal on area51 which appears to be coming along, and could do with your support if you would find it helpful. –  dmckee Sep 26 '11 at 20:20
