OK, I'm going with Edward on this one. He explained it better than my
university chemistry professor. :-)
Not that I understand the whole explanation but I'll just keep on using
that Kodak Indicator Stop Bath as long they keep making it. It's worked
just fine for me for years.

Assuming a base is a proton
