Which of the following statements is false?

a. When the hydrogen ion concentration decreases, the hydroxyl ion concentration also decreases.
b. When acids and bases are mixed, they react with each other to form water and a salt.
c. The pH of blood is slightly basic.
d. The more hydrogen ions in a solution, the more acidic the solution.

a. When the hydrogen ion concentration decreases, the hydroxyl ion concentration also decreases.

0 because theres a difference between pickled peppers and peers.
