Why is it impossible for a solution to become both more basic and more acidic at the same time? (1 point) a
H+ and OH− ions cannot exist in the same solution.

b
An increase in H+ concentration will decrease OH− concentration.

c
H+ and OH− react to form water (H2O).

d
Acids only release hydrogen ions in the presence of bases.
