A titration is a procedure for determining the concentration of a solution by allowing it to react with another solution of known concentration (called a standard solution). Acid-base reactions and oxidation-reduction reactions are used in titrations. For example, to find the concentration of HCl solution (an acid), a standard solution of NaOH (a base) is added to a measured volume of HCl from a calibrated tube called a buret. An indicator is also present and it will change color when all the acid has reacted. Using the concentration of the standard solution and the volume dispensed, we can calculate molarity of the HCl solution. II Review I Constants I Periodic Table Part A an A volume of 70.0 mL of aqueous potassium hydroxide (KOH) was titrated against a standard solution of sulfuric acid (H2 SO4). What was the molarity of the KOH solution if 20.2 mL of 1.50 M H2 S04 was needed? The equation is 2KOH(aq) + H2 SO (aq)→K2SO4 (aq) + 2H2 O(1) Express your answer with the appropriate units. > View Available Hint(s) µA molarity = Value Units Submit Part B Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide, H2 O2, can be titrated against a solution of potassium permanganate, KMNO4. The following equation represents the reaction: 2KMNO4 (aq) + H2O2(aq)+ 3H2 SO (aq)→ 302 (g) + 2MnSO (aq)+ K2SO4(aq) + 4H2O(1) A certain amount of hydrogen peroxide was dissolved in 100. mL of water and then titrated with 1.68 M KMNO4. What mass of H2 O2 was dissolved if the titration required 17.3 mL of the KMnO4 solution?
