1. 849 mg of a pure diprotic acid (this means that the acid is capable of donating two nydrogen ions or protons) was titrated with 12.32 mL of a 0.684 M potassium hydroxide solution. What is the molar mass of the acid? The balanced equation is: H2X 2 KOH K2X +2 HOH 2. The molarity of sulphuric acid in a fully charged car battery is 5.2 M. When fully discharged the molarity is 4.8 M. A 2.00 mL sample of battery acid was titrated with 31.26 mL of a 0.621 M sodium hydroxide solution. Does the battery need to be recharged? In the vernacular, what is the molarity of the battery acid? Document your answer. 3. A student titrated 38.00 mL of a 0.522 M sodium hydroxide solution with 25.00 mL of a 0.785 M hydrochloric acid solution. Which is the limiting reagent? How many mL of excess reactant will remain?

Question 2

1. 849 mg of a pure diprotic acid (this means that the acid is capable of donating two
nydrogen ions or protons) was titrated with 12.32 mL of a 0.684 M potassium hydroxide
solution. What is the molar mass of the acid? The balanced equation is:
H2X 2 KOH
K2X +2 HOH
2. The molarity of sulphuric acid in a fully charged car battery is 5.2 M. When fully
discharged the molarity is 4.8 M. A 2.00 mL sample of battery acid was titrated with
31.26 mL of a 0.621 M sodium hydroxide solution. Does the battery need to be
recharged? In the vernacular, what is the molarity of the battery acid? Document your
answer.
3. A student titrated 38.00 mL of a 0.522 M sodium hydroxide solution with 25.00 mL of
a 0.785 M hydrochloric acid solution. Which is the limiting reagent? How many mL of
excess reactant will remain?
