4.73 An auto mechanic spills 88 mL of 2.6 M H,SO4 solution from
an auto battery. How many milliliters of 1.6 M NaHCO3 must be
poured on the spill to react completely with the sulfuric acid?
4.74 Sodium hydroxide is used extensively in acid-base titrations
because it is a strong, inexpensive base. A sodium hydroxide solu-
tion was standardized by titrating 25.00 mL of 0.1528 M standard
hydrochloric acid. The initial buret reading of the sodium hydrox-
ide was 2.24 mL, and the final reading was 39.21 mL. What was
the molarity of the base solution?

adding an excess of base and then "back-titrating" the excess. A
