When jump-starting a car with a dead battery, the ground jumper should be attached to a remote part of the engine block. Why?
0.1724g of a mineral containing MnO₂ was dissolved and then treated with excess iodide according to the following unbalanced reaction: MnO2(s) + H+ → Mn²+ + I2 + H₂O The I₂ released was titrated with a solution of Na₂S2O3 0.07320 mol/L, requiring 14.65 mL to reach the point end of degree a) Determine the percentage of MnO₂ in the ore. b) When iodine solutions are used as titrants these are prepared by dissolving 1₂ in concentrated KI. Explain the reason for the need for KI in the preparation of these solutions?
A solution containing 0.402 49 g of CoCl2 ? xH2O (a solid with an unknown number of waters of hydration) was exhaustively electrolyzed to deposit 0.099 37 g of metallic cobalt on a platinum cathode by the reaction Co21 1 2e2¡Co1s2. Calculate the number of moles of water per mole of cobalt in thereagent. A good approach is to find moles of Co, moles of CoCl2, mass of CoCl2, and, by difference, mass of H2O in the sample.
For Redox Analysis of Iron... ~0.02 M of potassium dichromate is prepared as titrant for dried unknown. ~.3 g of sample, 50ml of 6M HCl, 20mL SnCl2, 10 mL of saturated HgCl2 solution, 60 mL of 3M H2SO4, 15mL of concentrated H3PO4, 100mL DI water. HCl (+ heat in fumehood until samples dissolves), SnCl2 (added with pipet until solution changes from yellow to colorless/light green with 3 drops in excess), HgCl2 (after cooling), H2SO4, H3PO4, DI Water, is added to the sample solution with 8 drops of diphenylamine sulfonate indicator then titrated with the potassium dichromate to a violet blue endpoint. 4. Why is it necessary to carry out the reduction of iron and then the titration, before going on to the next sample 5. If you look carefully, there are pieces of tin metal on the bottom of the SnCl2 reagent solution. Why is it there?

How would you prepare a complete anlaysis procedure using KMnO4 as the oxidant instead of K2CrO7? Include sample and solution preparation, approximate weights of samples and reagents, procedure and chemical reactions. In particular what is the purpose of the Zimmerman Reinhardt Reagent?
Fine particles of metallic iron can be injected underground to remediate pollution of underground aquifers by the industrial solvent trichloroethane. In one experiment, 2400L of an aqueous emulsion containing ~480 kg of Fe(0) consumed 17.0 kg of trichloroethane in 5 months. Write a balanced reaction using H2O and H+ to complete the balancing. What percentage of injected iron was used by this reaction in 5 months? Fe + C2HCl3 ---> Fe2+ + C2H4 + Cl-
For a redox analysis of iron, how do you calculate the % (weight/weight) with a mass of the K2Cr2O7 that was diulted to 250.00ml is 1.488 grams, mass of unknown is 0.2839g, and the vol. titrant given was 24.38 ml?
A sample of impure tin of mass 0.535 g is dissolved in strong acidto give a solution of Sn2+. The solution is then titrated with a0.0448 M solution of NO3-, which is reduced to NO(g). Theequivalence point is reached upon the addition of 0.0344 L of theNO3- solution. Find the percent by mass of tin in the originalsample, assuming that it contains no other reducing agents.
A precipitate of AgCl + AgBr weighs 0.8132 g. On heating on a current of Cl2, the AgBr is converted to AgCl, the mixture loses 0.1450 g in wt. Find the percentage Cl in the original sample.
a. The alkalinity of natural waters is usually controlled by OH- (MW = 17.01 g/mole), CO3-2 (MW = 60.01 g/mole), and HCO3- (MW = 61.01 g/mole), which may be present singularly or in combination. Titrating a 100.0-mL sample to a phenolphthalein endpoint requires 18.67 mL of a 0.02812 M solution of HCl. A second 100.0 mL aliquot requires 48.12 mL of the same titrant to reach the methyl orange endpoint. The composition of the sample is ___________ ppm CO3-2 and _________ ppm HCO3- Note: Express final answers using least number of significant figures. b. A 1.963-g sample of an alloy sample requires 27.19 mL of 0.1078 M KSCN to reach the endpoint, the percent Ag (MW = 107.87 g/mole) in the alloy is_________ % ? Note: Express final answer using least number of significant figures
A sample of impure KI weighing 0.600 g is dissolved in water, the solution acidified, and 25.00 mL of 0.0400 M KIO3 (an excess ) is added. The iodate is reduced to I2 and the iodide is oxidized to I, The I2 is boiled off, the solution cooled, and an excess of pure KI is added to react with the unused KIO3. The I2 produced is titrated with 40.38 mL of 0.1053 N thiosulfate. Write the equations for the reactions which occurred and calculate the percentage of KI in the sample.
