Write and balance neutralization reactions for the following: a) sodium hydroxide reacting with hydroiodic acid b) hydrochloric acid reacting with calcium hydroxide You need to know the molarity of H2SO4 in a reaction vessel of approximately 50 mL. You decide to remove and titrate a 10.00 mL sample of the acid. The titration required 33.26 mL of standard 0.2643 M NaOH to reach the endpoint. What is the molarity of the H2SO4 in the reaction vessel?
A: The normality of an aqueous solution of hydrochloric acid is determined by titration with a 0.161 N sodium hydroxide solution If 26.6 mL of sodium hydroxide are required to neutralize 14.2 mL of the acid, what is the normality of the hydrochloric acid solution?__N B: The normality of an aqueous solution of hydroiodic acid is determined by titration with a 6.19×10-2 N barium hydroxide solution. If 38.3 mL of barium hydroxide are required to neutralize 19.6 mL of the...
