Dwain is drinking a cup of coffee which has a pH of 5. Compare Dwain's coffee to his friend's coffee which has a pH of 6
What will be an ideal response?
Each single digit change on the pH scale corresponds to a 10-fold change in hydrogen ion concentration. Dwain's coffee, with a pH of 5, is 10 times more acidic than his friend's coffee, with a pH of 6. The hydrogen ion concentration increases 10-fold from a pH of 6 to a pH of 5.
