8.2 Strong and Weak Acids & Bases

Question 1

Strong acid

Answer 1

Acid that ionizes 100% in water, making hydrogen ions

Question 2

Weak acid

Answer 2

Acid that only partly ionizes in water, making hydrogen ions

Question 3

Weak base

Answer 3

Only partially reacts with water to produce hydroxide ions

Question 4

Base ionization constant (Kb)

Answer 4

The EQ constant for the ionization of a base: also called the base disassociation constant

Question 5

Organic base

Answer 5

Organic compound that increase concentration of hydroxide ions in aqueous solution

Question 6

Autoionization of water

Answer 6

The transfer of hydrogen ion from one water molecule to another

Question 7

Ion-product constant for water (Kw)

Answer 7

The EQ constant for the autoionization of water

Question 8

pH

Answer 8

negative log of concentration of hydrogen ions in an aqueous solution

Question 9

pOH

Answer 9

Negative log of concentration of hydroxide ions in an aqueous solution

Question 10

pH meter

Answer 10

Device that measures acidity of alkalinity of a solution electronically and displays the result as a pH value

Question 11

Acid-base indicator

Answer 11

A substance that changes colour within a specific pH range
