Søren Peder Lauritz Sørensen introduced the notion pf pH, don't know if there is a commonly accepted person for discovering pH qualities in red cabbage.

They are the same in their function, to be able to differentiate between acidic or basidic substances.

I would think the main difference is in accuracy with which you can determine the pH of cetrain substances.

Red cabbage paper won't be able to be nearly as accurate as a pH paper commercially produced.
