Question 8

Water Dissociation Constant

Answer 8

Kw = 10^-14 at 298K
Kw=Ka * Kb

Question 9

pH equation

Answer 9

pH= -log[H+]

Question 10

pOH equation

Answer 10

pOH = -log[OH-]

Question 11

[H+]

Answer 11

[H+] = 10^-pH

Question 12

pH + pOH

Answer 12

pH + pOH = 14

Question 13

p scale value approximation

Answer 13

-log (A * 10^-B)
p value = -(B + 0.A)

Question 14

___ Acids/Bases dissociate completely
___ Acids/Bases do not dissociate completely

Answer 14

• Strong = dissociate completely
• Weak = do not dissociate completely

Question 15

Acid Dissociation Equation & Constant

Answer 15

Equation:
Ka=([H3O+][A-])/[HA]

Constant:
pKa = -log(Ka)

Question 16

Base Dissociation Equation & Constant

Answer 16

Equation:
Kb=([B+][OH-])/[BOH]

Constant:
pKb = -log(Kb)

Question 17

pKa + pKb

Answer 17

pKa + pKb = pKw = 14
