An aqueous solution of hydrochloric acid is standardized by titration with a 0.1

Question

An aqueous solution of hydrochloric acid is standardized by titration with a 0.176 M solution of potassium hydroxide. If 20.5 mL of base are required to neutralize 27.6 mL of the acid, what is the molarity of the hydrochloric acid solution?

_________M hydrochloric acid

An aqueous solution of hydroiodic acid is standardized by titration with a 0.154 M solution of sodium hydroxide.
If 23.9 mL of base are required to neutralize 19.0 mL of the acid, what is the molarity of the hydroiodic acid solution? _________M hydroiodic acid

An aqueous solution of barium hydroxide is standardized by titration with a 0.119 M solution of hydrobromic acid.
If 13.7 mL of base are required to neutralize 24.7 mL of the acid, what is the molarity of the barium hydroxide solution?

_______M barium hydroxide

Explanation / Answer

M1*V1 = M2*V2

a.) M1*27.6 /1000 = 0.176*20.5/1000

M1 = 0.1307

b.) M1*19/1000 = 0.154*23.9/1000

M1 = 0.1937

c.) 0.119*24.7 = 2*M2*13.7

M2 = 0.10727
