1. Write the reaction of phosphoric acid with sodium hydroxide: use only the first dissociation of the acid.

2. A student used 8.75ml of 0.05M NaOH to titrate 48.65mL of cola to the first equivalence point. (using a pH meter)

a. How many moles of NaOH were used?

b. How many moles of H3PO4 were in the cola sample?

c. What is teh concentration of H3PO4 in the cola sample?

3. Explain how you might do this same titration if you did not have a pH meter.

4. Why do you think that the sample titration curve of acetic acid titrated with NaOH would look different than a titration curve for the tirtration of phosphoric acid with NaOH?
