The amount of I5 (aq) in a solution can be determined by titration with a solution containing a known concentration of S₂O3(aq) (thiosulfate ion). The determination is based on the net ionic equation 2S₂O3(aq) + 15 (aq) - SO2 (aq) +31 (aq) Given that it requires 41.0 mL of 0.450 M Na₂S₂O3(aq) to titrate a 20.0 mL sample of 15 (aq), calculate the molarity of 15 (aq) i the solution. [13] = M

When jump-starting a car with a dead battery, the ground jumper should be attached to a remote part of the engine block. Why?
Ascorbic acid (Vitamin C, MW = 176.126g/mol) is a reducing agent, reacting as follows: C6H8O6 → C6H6O6 + 2H+ + 2e It can be determined by oxidation with a standard solution of I2. A 200.0-mL sample of a citrus fruit drink is acidified, and 10.00mL of 0.0500 M I2 is added. After the reaction is complete the excess I2 is titrated with 38.62 mL of 0.0120 M Na2S2O3 . Calculate the number of milligrams of ascorbic acid per milliliter of fruit drink. I2 +2e → 2I- I2 + 2Na2S2O3 → 2NaI + Na2S4O6
The SO2 present in air is mainly responsible for the phenomenon of acid rain. The concentration of SO2 can be determined by titrating against a standard permanganate solution as follows: 5SO2 + 2MnO4- + 2H2O ---> 5SO42- + 2Ms2 + 4H+ Calculate the number of grams of SO2 in a sample of air if 4.90mL of 0.00700M KMnO4 solution are required for the titration. Be sure your answer has the correct number of significant digits.
25.00 mL of a solution containing KIO4 is treated with excess potassium iodide. IO4- + 8H+ + 7I- → 4I2 + 4H2O The resulting solution is titrated with 0.15 M sodium thiosulfate pentahydrate. The average titre was 21.76 mL. I2 + 2S2O32- → 2I- + S4O62- What is the concentration of the sodium thiosulfate solution as a percentage (w/v)
The tetraethyl lead [Pb(C2H5)4] in a 25.00 mL sample of aviation gasoline was shaken with 15.00 mL of 0.02158 M I2. (Hint: one mole of I2 reacts with one mole of the tetraethyl lead). After the reaction was complete, the unused I2 was titrated with 4.86 mL of 0.02944 M thiosulfate solution. Calculate the weight in milligrams of [Pb(C2H5)4] (MW = 323.4 g/mol) in each liter of gasoline. Assign an oxidation number to the element specified in the compound or ion below: N:N2O2 N:NH4+
When 25.00 mL of unknown were passed through a Jones reductor, molybdate ion (MoO4^2-) was converted into Mo3+. The filtrate required 16.43 mL of 0.010 33 M KMnO4 to reach the purple end point. MnO4- + Mo3+ --> Mn2+ + MoO2^2+. A blank required 0.04 mL. Balance the reaction and find the molarity of molybdate in the unknown.
A student weighs out 1.118g of impure HPT, dissolves the sample in deionized water and tirates it with 0.1001M of NaOH solution. If the titration requires 2710mL of the NaOH solution, and none of the impurities react with NaOH, what is the percent KHP in the sample? I'm confused why none of the impurities would react. I multipled 0.1001M by 2.71L and got 0.2172M of NaOH. As it's 1:1 ratio, shouldn't the point of equivalence be 0.2712 mol of KHP? But I do not have the volume of KHP so how can I calculate the molarity with only grams (which can be turned into mol) and no volume?
What is the solubility (in g/L) for PbBr2(s) in a 1.00 L solution that has 251 g Pb(NO3)2 already dissolved in it? The Ksp for PbBr2 is 5.67 × 10-6. If you need more room, use a second sheet.
The tetraethyl lead Pb(C2H5)4 in a 25.00 mL sample of aviation gasoline was shaken with 15.00 mL of 0.02179 M I2. (Hint: one mole of I2 reacts with one mole of the tetraethyl lead). After the reaction was complete, the unused I2 was titrated with 7.37 mL of 0.02959 M thiosulfate solution. Calculate the weight of Pb(C2H5)4 (MW = 323.4 g/mol) in each liter of gasoline.
