Lewis defined them as electron pair acceptors, while Bronsted and Lowry defined them as proton donors, contrasting them with proton receivers, or bases.
A constant named for these substances appears in the Henderson-Hasselbalch (HOSS-el-bock) equation. That constant, their namesake "dissociation constant," measures their strength in solution. Lewis defined them as electron pair acceptors, while Bronsted and Lowry defined them as proton donors, contrasting them with proton receivers, or bases. For 10 points, name these substances which have a pH of less than seven.
