Question 1

STRONG ACID X STRONG BASE
pH at 10mL of added base

Answer 1

Calculate the difference in moles between the acid and base moles (using volume = 10mL for base)

Use mol difference and the total volume to find the concentration to find pH

Question 2

WEAK ACID X STRONG BASE
Initial pH

Answer 2

ICE table for the weak acid to find pH with Ka value

Question 3

WEAK ACID X STRONG BASE
pH at 5mL of added base

Answer 3

Use Henderson Hasselbalch
- you do the difference in the moles for acid

Question 4

WEAK ACID X STRONG BASE
pH at equivalence point

Answer 4

Acid turns into conjugate base, use ICE table of conjugate base and determine the pH value of the acid

• use new concentration for the value of conjugate base concentration

Question 5

WEAK ACID X STRONG BASE
pH after adding 5mL of base past equivalence point

Answer 5

Determine the moles of base using the 5mL as part of total volume (C=n/v)
Determine the concentration of OH and find pOH using it

Question 6

STRONG ACID X WEAK BASE
Initial pH

Answer 6

ICE table with the weak base to find pOH with Ka value

Question 7

STRONG ACID X WEAK BASE
pH at 5mL added acid

Answer 7

Determine if mol ratio is within buffer ratio
Find the difference in mol amount for the amount of moles of base
Use henderson hasselbalch

Question 8

STRONG ACID X WEAK BASE
pH at equivalence point

Answer 8

Base turns into conjugate acid, use ICE table of conjugate acid and determine the pH value

Question 9

STRONG ACID X WEAK BASE
pH past equivalence point

Answer 9

All of the base turns into conjugate acid
Use ICE table and determine the pH
