The pH of a substance is Calculate the following: H+ concentration OH- concentration pOH What is the type of solution?
27
The pH of a substance is Calculate the following: H+ concentration [H+] = = 2.75x10-4M OH- concentration poH = =10.44 [OH-]= =3.63x10-4M pOH = What is the type of solution? Acid
28
Compare and contrast strength and concentration of acids and bases
29
Compare and contrast strength and concentration of acids and bases
Strength is how well the acid or base dissociates or ionizes in water (what percentage of the acid breaks apart into ions). The stronger the acid, the more it ionizes. Concentration is a measure of how much acid or base is found in the water regardless of how much is dissociates or ionizes.
