Chemistry The pH Scale and Chemistry
The pH scale measures how acidic or basic a solution is, ranging from 0 to 14. Pure water has a pH of 7 (neutral). Each whole number represents a 10-fold change in acidity. Our blood must maintain a pH of 7.35-7.45 to survive - even small deviations can be fatal.
