Question 1

A 19.0-mL sample of tartaric acid is titrated to a phenolphthalein endpoint with 20. mL of 1.0 M NaOH. Assuming tartaric acid is diprotic, what is the molarity of the acid?

◦ 1.0 M
◦ 0.53 M
◦ 2.0 M
◦ 1.05 M
◦ Additional information is needed.

Question 2

A 2.19-g sample of an acid, H₂X, requires 45.0 mL of a 0.500 M NaOH solution for complete reaction (removing both protons). The molar mass of the acid is:

◦ 97
◦ 240
◦ 217
◦ 195
