Titration

Question 1

Determining the major species in solution besides water

Answer 1

1. multiply the volume by the molarity
2. divide the base by acid

Question 2

Finding the Ka of an acid

Answer 2

the pH = pea at halfway to E.P
inverse log of pKa

Question 3

Calculate the pH of a solution

Answer 3

1. take dilution into account (the molarity)(added volume/total volume)
2. plug into H/H equation and use the dilution values

Question 4

Finding the pH after the addition of a acid/base

Answer 4

1. multiply the dilution value of original compounds by original total volume
2. multiply the molarity of added compound by the volume
3. write out equation; if added compound is a base, OH- is in reactant and H2O is in products
4. create ICFF table; for initial plug in the values calculating in steps 1 and 2
5. subtract by the added compound
6. for the final F divide the value bu TOTAL volume
7. plug into H/H formula

Question 5

calculating the Ka of a weak acid

Answer 5

1. take dilution into account for each compound
2. write out the equation and create a ICFF table. For initial plug in the dilution values and subtract by the limiting reactant.
3. plug into H/H equation
