Question

A. A 11.3 g sample of an aqueous solution of hydrobromic acid contains an unknown amount of the acid.
If 12.8 mL of 0.122 M barium hydroxide are required to neutralize the hydrobromic acid, what is the percent by mass ofhydrobromic acid in the mixture?

= % by mass

B. A 10.4 g sample of an aqueous solution of nitric acid contains an unknown amount of the acid.
If 25.9 mL of 0.403 M barium hydroxide are required to neutralize the nitric acid, what is the percent by mass of nitric acid in the mixture?

= % by mass

C. A 13.3 g sample of an aqueous solution of perchloric acid contains an unknown amount of the acid.
If 21.5 mL of 0.972 M sodium hydroxide are required to neutralize the perchloric acid, what is the percent by mass of perchloric acid in the mixture?

= % by mass

D. An aqueous solution of hydrobromic acid is standardized by titration with a 0.114 M solution of barium hydroxide.

If 24.8 mL of base are required to neutralize 11.8 mL of the acid, what is the molarity of the hydrobromic acid solution?

= M hydrobromic acid

E. An aqueous solution of nitric acid is standardized by titration with a 0.179 M solution of barium hydroxide.

If 14.6 mL of base are required to neutralize 17.6 mL of the acid, what is the molarity of the nitric acid solution?

= M nitric acid

F.   An aqueous solution of calcium hydroxide is standardized by titration with a 0.158 M solution of perchloric acid.

If 18.0 mL of base are required to neutralize 29.0 mL of the acid, what is the molarity of the calcium hydroxide solution?

= M calcium hydroxide

G. What volume of a 0.114 M barium hydroxide solution is required to neutralize 24.8 mL of a 0.127 M hydrobromic acid solution?

= mL barium hydroxide

H. What volume of a 0.179 M barium hydroxide solution is required to neutralize 14.6 mL of a 0.214 M nitric acid solution?

= mL barium hydroxide

I. What volume of a 0.385 M perchloric acid solution is required to neutralize 18.0 mL of a 0.158 M calcium hydroxide solution?

= mL perchloric acid
