Acid And Bases

Question 1

Bronsted-Lowry definition of acid and a base

Answer 1

Acid: proton donor
Base: accepts protons

Question 2

Conjugate acid

Answer 2

The compound formed when a proton is transferred to the base

Question 3

Conjugate base

Answer 3

The initial acid minus a proton

Question 4

Oxyacids

Answer 4

Most acids occur in nature
Acid whose hydrogen is bound to an oxygen
Ex: phosphoric acid, acetic acid

Question 5

Amphoteric

Answer 5

Substances that can behave either as an acid or a base

Ex: water, Dihydrogen phosphate H2PO4-, HSO4- (hydrogen sulfate)

Question 6

Self ionization of water

Answer 6

H2O+H2O H3O++OH-

Question 7

Arrhenius definitions of acid and bases

Answer 7

Acid: anything that produces H+ ions in solution
Base: a substance the produces OH- ions in solutions

Question 8

Ion product constant

Answer 8

-14
[H3O+]x[OH-]= 1.0x10
If h3o increases, oh must decrease so that the constant remains the same.

Question 9

Acidic, basic, and neutral solutions

Answer 9

Neutral solution——– [H+]=[OH-]
Acidic solution——— [H+]>[OH-]
basic solution———- [H+]

Question 10

The ph scale

Answer 10

The concentrations of h+ and oh- are generally very small so pH Uses logs to express the small numbers more conveniently
