Chapter 15 Basic Chemistry Vocab:acids, Bases, And Ionic Equations

Front 1

Compounds that change color in the presence of certain chemicals, such as acids and bases. Litmus paper is the best known of these

Back 1

Indicators

Front 2

Any substance that releases hydrogen ions (H+) when dissolved in water

Back 2

Acid (Arrhenius definition)

Front 3

Any substance that releases hydroxide ions (OH-) when dissolved in water

Back 3

Base (Arrhenius definition)

Front 4

Any substance that can donate a proton (H+) to some other substance

Back 4

Acid (Bronsted-Lowry definition)

Front 5

Any substance that can accept a proton (H+) from another substance

Back 5

Base (Bronsted-Lowry definition)

Front 6

Any substance that can act as an acid or base, depending on the nature of the solution; water is the best known of this

Back 6

Amphoteric substance

Front 7

Species formed when a proton (H+) is added to a base

Back 7

Conjugate acid

Front 8

Species formed when a proton (H+) is removed from an acid

Back 8

Conjugate base

Front 9

Process in which the ions in ionic substances separate when acted on by a solvent

Back 9

Dissociation

Front 10

Process in which covalent compounds dissolve to produce ions in aqueous solution

Back 10

Ionization

Front 11

Point at which an acid or base is exactly neutralized in the titration process

Back 11

Equivalence point

Front 12

Point at which indicator in an acid-base titration change color. It is often the same as the equivalence point, but not always

Back 12

End point

Front 13

Quantitative way of expressing the acidic or basic nature of solutions using the negative logarithmic values of their hydrogen ion (H+) concentrations

Back 13

pH

Front 14

Quantitative way of expressing the acidic or basic nature of solutions using the negative logarithmic values of their hydroxide ion (OH-) comcentrations

Back 14

pOH

Front 15

Substances that produce ions in aqueous solution and solutions that conduct an electric current.

Back 15

Electrolytes

Front 16

Substances that do not produce ions in aqueous solution and solutions that do not conduct an electric current

Back 16

Nonelectrolytes

Front 17

Express chemical reactions involving compounds that exist mostly in ionic form in aqueous solution
