- Six iron tablets containing FESO4-7H,0 were dissolved in 100-ml of 0.1 M HNO; with gentle heating. All of the Fe- is converted to Fe by the strong oxidizıng conditions. After the solution had cooled to room temperature 2.5-ml of 35wt% NH4OH was added. The precipitate Fe;O3-xH,O that was filtered weighed 0.345 g. Thermogravimetric analysis of the crude product showed a 10.5% weight loss below 150 C How much iron was in each of the tablets? Report the average mg-Fe per tablet?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.Complete and balance the following redax equation.
