A ferric phosphate solution is prepared by adding 2.4 g of ferric phosphate to a volumetric flask and bringing the final volume to 1 L by adding water having a phosphate concentration of 1 mg *L^-1. What is the concentration of soluble iron in this solution? (Assume temp of solution is 25 degs celc)
Consider a saturated solution of calcium fluoride in 0.075 M potassium nitrate. Complete the following tasks, and then answer the question. (Note: Your textbook may not employ the terms Kspo and Ksp'. Please refer to the lecture notes.)
The redox reaction of peroxydisulfate with iodide has been used for many years as part of the iodine clock reaction which introduces students to kinetics. If Eºcell = 1.587 V and Eº of the anode half-cell is 0.536 V, what is Eº of the cathode half..

Calculate the wavelength of a photon in nm emitted by a hydrogen atom when its electron drops from the n=5 state to the n=3 state
A solution is prepared by mixing 79.0 mL of 5.00 M HCl and 34.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+ ], [OH - ], and the pH for this solution.
A 2.000 ton block of aluminum at room temperature (22 degrees celsius) is struck by lightning. The lightning transfers 8.000 x 10^6 kJ of energy to the block
Based on the following values, the value for Delta S for the decomposition of one mole of gaseous sulfur trioxide to give solid sulfur and oxygen gas is: S(s): S = 31.88 O2(g): S = 205.0 SO3(g): S = 256.2
Your lab partner is typically spot-on, but today they are having an awful day. Instead of using concentrated sulfuric acid in this exercise, they used concentrated hydrochloric acid.
