(b) If a 1.50−g sample of plant matter requires 39.0 mL of 0.0500 M KMnO4 solution to reach the equivalence point, what is the percent by mass of H2C2O4 in the sample
1. (4p) In an acidic aqueous solution, Fe2+ ions are oxidized to Fe3+ ions by MnO4": 5Fe2+(aq) + MnO4 (aq) + 8H(aq) → 5Fe3+ (aq) + Mn2(aq) + 4H2O(1) In part A of the experiment, suppose that 1.067 g of Fe(NH4)2(SO4)2.6H2O(s) are placed in a 250 ml Erlenmeyer flask to which 20 mL of water and 8 mL of 3 M H2SO4(aq) are added. The solution was titrated to the end point by adding 26.89 mL of KMnO4(aq) from the...
An acidified solution of manganate (VII) of permanganate ions, MnO4-, is a strong oxidising agent and will be used in an experiment to determine the percentage of iron in a sample of ammonium iron (II) sulfate hexahydrate. The titration is self-indicating because at the equivalence point the products are a different colour than the original reactants. The two half reactions are: MnO4-(aq) + 8H+(aq) + 5e- ---> Mn2+(aq) + 4H2O(l) Fe^2+(aq) ---> Fe^3+(aq) + e- a) What is a redox...
Consider the titration of a 22.0 mL sample of 0.110 molL−1 CH3COOH (Ka=1.8×10−5) with 0.125 molL−1 NaOH. Determine each quantity: Part A the initial pH pH = 2.85 Part B the volume of added base required to reach the equivalence point V = 19.4 mL Part C the pH at 4.0 mL of added base pH = 4.16 Part D the pH at one-half of the equivalence point pH = 4.74 Part E the pH at the equivalence point pH...
QUESTION 1 Minnie Mouse did the Ka by Titrimetry experiment last week. Minnie used 28.63 mL of 0.136 M sodium hydroxide to reach the equivalence point when she titrated 0.3062 g of an unknown monoprotic acid. What is the number of moles of acid that were used? QUESTION 2 The Iron in a sample of iron ore can be converted completely to Fe2+ in aqueous solution, and this solution can then be titrated with KMnO4, as shown: MnO4(q) + 6...
The standardization of KMnO4 solution, if the magnetic stir bar was dropped into the flask, and some FAS solution splashed out, how would the calculation for the molarity of KMNO4 be affected? The calculated molarity of KMnO4 would be: Lower. Less FAS would need less MnO4-, therefore, the reduced volume would result in a smaller M. Unchanged. Lower. More FAS would need less MnO4-, therefore, the increased volume would result in a smaller M. Higher. Less FAS would need less MnO4-, therefore, the...
