title: Which pH paper?
abstract: Five different brands of pH indicator paper were used by 20 anaesthetists to test four buffer solutions. There were significantly fewer correct answers with two papers than with the other three. The worst paper in the study (Whatman full range) gave only 20% correct answers, compared with 92.5% from the best (Merck).
