Which of the following describes the properties of a base?
A. are generally proton acceptors
B. produce OH- ions in solution
C. are electron pair donors
D. may include all of these characteristics
I would say B, because in normal reactions (non-nuclear) protons are not moved around, and according to Bronsted-Lowry theory, bases accept ELECTRONS. Thus the answer cannot be A, C, or D and must be B.
