In a test of pH levels, a baking soda has a pH of 9 and bleach has a pH of 12. What is true about there relationship?

• Both of the solution are bases

• Both of the solution are acids

• The Baking soda is an acid and the Bleach is a base

• The baking soda is a base and the Bleach is an acid.

Water has a neutral because

• it has more H+ ions than OH-

• it has more OH- ions than H+

• it does not produce any ions

• it has an equal amount of H+ and OH- in solution

A substance that does not dissociate completely. Ranges from 4-7 on the pH scale.

• Strong Acid
