please box answers A volume of 90.0 mL of aqueous potassium hydroxide (KOH) was titrated against a standard solution of sulfuric acid (H2SO). What was the molarity of theKOH solution it 12.2 mL of 1.50 M H2SO, was needed? The equation is2KOH(aq) + H,SO. (aq)-»K2SO, (uq) + 2H, O(1)Express your answer with the appropriate units.> View Available Hint(s)molarity = 0.407 MSubmitPrevious AnswersCorrectThe solution in the buret (in this case, H2SO4) is called the itrant. The sample in the flask (in this case, KOH) is called the analyte. The stage in atitration when the exact volume of solution needed to complete the reaction has been added is called the stoichiometric point or equivalence point. Todetect the equivalence point, a few drops of an acid-base indicator are added to the analyte before the titration.Part BRedox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide, H2O2. can betitrated against a solution of potassium permanganate, KMNO,. The following equation represents the reaction:2KMNO, (aq) + H,O, (aq) + 3H,SO. (aq)→30, (g) + 2MnSO, (aq) + K,SO. (aq) + 4H,O(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 H,O2 was dissolved if thetitration required 13.3 mL of the KMNO, solution?Express your answer with the appropriate units.> View Avallable Hint(s) Review I Constants I Periodic TableAs a food chemist for a major potato chip company, you are responsible for determining the salt content of new potato chip products for the packaging label. Thepotato chips are seasoned with table salt, NaCl. You weigh out a handful of the chips, boil them in water to extract the salt, and then filter the boiled chips toremove the soggy chip pieces. You then analyze the chip filtrate for CIT concentration using the Mohr method.First you prepare a solution of silver nitrate,AGNO,, and titrate it against 0.500 g of KCI using the Mohr method. You tind that it takes 63.0 mlL of AgNO, titrant to reach the equivalence point of thereaction. You then use the same silver nitrate solution to analyze the chip filtrate in a Mohr reaction, finding that the solution yields a rusty brown precipitate when45.7 mL of titrant is added.Part AIf the sample of chips used to make the filtrate weighed 92.0 g. how much NaCl is present in ofe serving (115 g) of chips?Express your answer to three significant figures and include the appropriate units.> View Available Hint(s)HAsalt/serving =ValueUnits

How do you determine concentration of an unknown using standard addition method? For example, if you have five solutions with varying amounts of the unknown, 0 mL, 10 mL, 20 mL, 30 mL, and 40 mL, per 100 mL of 0.05 M solution and absorbance values for each, how would you use this to find concentration of the unknown. Would the unknown concentration be the slope of the standard addition model graph, or do you have to determine concentration of all five solutions and use these concentrations and the absorbance values to create an absrobance vs concentration graph? If so, would the slope of that graph be the concentration of the unknown.
