This thread is a bit of a puzzle, not a request for philosophy.
In the course of learning about buffer solutions I stumbled across this Khan University lecture which ended up revealing an interesting and dangerous trap for young and old players alike that are involved in technical fields - including electronics.
While this is a chemistry lecture you don't need to know chemistry to figure out the trap. You do need to know some basic algebra - including logarithms.
After the professor has derived his text book equation (H-H), he shows that the formula identifies an "amazing" relationship between the moles of an acid and base and the ph of the buffer solution. He later realizes his conclusion was wrong and to his credit posts his mistake in the video. He uses a thought experiment to show that his conclusion made no sense, but he never identified his fundamental mistake.
Can you figure it out?
Watch the video, "Buffers", starting at time 9:45 - it is about 8 minutes long.
Don't look at my next post if you want to solve the puzzle yourself.
