An aqueous solution of hydroiodic acid is standardized by titration with a 0.139 M solution of barium hydroxide.If 13.4 mL of base are required to neutralize 29.3 mL of the acid, what is the molarity of the hydroiodic acid solution?
H2. Titrations are performed by a scientist in the laboratory as follows: a solution of deuterated hydrochloric acid contains 1.08 g DCl in 750 ml of deionised, distilled water. An average amount of 14.95 ml of the DCl(aq) solution is titrated with 25.0 ml of Ca(OH)2 to produce an endpoint (as determined by an appropriate indicator). What is the molarity of the Ca(OH)2 solution? You must include all of your calculations Please give typed answer

A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 30. mg of oxalic acid (H,C,0,), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilled water. The student then titrates the oxalic acid solution with his sodium hydroxide solution. When the titration reaches the equivalence point, the student finds he has used 62.3 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 2 significant digits. x10
