Strong/Weak Acids And Bases

Question 1

Acids

Answer 1

pH 1-6
Excess of H3O+ ions
Proton (H+) donors
Turns litmus red

Question 2

Bases

Answer 2

pH 8-14
Excess of OH- ions
Proton (H+) acceptors
Turns litmus blue

Question 3

Strong Acids/Bases

Answer 3

Further from 7 on pH scale
Larger amount of H3O+/OH- ions
Faster rates of reaction
Good conductors of electricity
Fully dissociate

Answer 4

Closer to 7 on pH scale
Lesser amount of H3O+/OH- ions
Slower rates of reaction
Poor conductors of electricity
Partially dissociate

Answer 21

Weak Base

Question 22

HS-

Answer 22

Weak Base

Question 23

NH4OH

Answer 23

Weak Base

Question 24

Conjugate Acids and Bases

Answer 24

A pair of species found in an equilibrium which differs by one H+ ion (HCOO- and HCOOH)

Question 25

Equations for Strong Acids

Answer 25

pH = -log[H3O+]
[H3O+] = 10^-pH

Question 26

Equations of Strong Bases

Answer 26

Kw = [OH-][H3O+]
[H3O+] = Kw/[OH-}
[OH-] = Kw/[H3O+]
