1. Unit 6: Acid-Base Applications Lesson 1: Acid-Base Titrations

2. Example 1: Finding Unknown Concentration
In the reaction
H2SO4 + 2 NaOH → Na2SO4 + 2 H2O ,
an equivalence point occurs when mL of M NaOH is added to a mL portion of H2SO4. What is the [H2SO4]?
10 min

3. Example 2: Finding Extent of Neutralization
An equivalence point is reached by reacting mL of M NaOH with mL of M H4P2O7. How many protons are removed from the H4P2O7 on the average and what is the balanced equation for the reaction?
10 min

4. Brain Break! Find as many words as you can using the letters shown, always using the middle letter. What’s the 9-letter word?
ambulance

5. Example 3: Finding Purity of a Sample
A g sample of impure NaHSO4 is diluted to mL. A mL sample of the solution is titrated with mL of M NaOH. What is the percentage purity of the NaHSO4?
10 min

6. Example 4: Finding Molar Mass
A g sample of unknown monoprotic acid is diluted to mL. A mL sample of the acid solution is titrated with mL of M KOH. What is the molar mass of the acid?
10 min
