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 solubon) Acid-base reactions and oxidation-reduction reactions are used in strations. For example, to find the concentration of an HCl solution (an acid) a standard solution of NaOH (a base) is added to a measured volume of HCI 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 HCI solution Part A A volume of 90.0 ml, of aqueous potassium hydroxide (KOH) was lirated against standard solution of sufuric acid (ISO,) Whor was the molarity of the KOH solution 22.7 ml, of 1.50 Af HSO, was needed? The equation is Express your answer with the appropriate units. #A 2KOH(aq) +H₂SO, (q)-K₂80,(g) +21,00) molarity Value Units ?

For example, to find the concentration of an HC3 solution (an ach), a standard solution of NaOH (a base) is added to a measured volume of HC1 from a calorated tube called a buret. An indicator is also present and it will change color when all the agd has reacted. Using the concentration of the standard solution and the volume deponosod, we can calculate molarity of the HCI solution Part B Redox strations are used to determine the amounts of oxidizing and reducing agents in soution For example, a solution of hydrogen per H₂Oy, can be titrated against a solution of potasskam permanganate, KMnO, The forlowing spation represents the reaction 2KMnO4(aq) +11,Os(aq) + 3H,SO,(aq)-+ mass of H₂O= Acertain amount of hydrogen peroxide was dissolved in 100 mil. of water and then thated with 108 M KMnO, What mass of Oy was dissolved if the titration required 19.3 ml, of the KMBO, solution? Express your answer with the appropriate units. Value 30s (g) + 2MuSO,(g) + K₂SO4(q) + 4H₂O() + ✦ C? Units
