Sally has constructed a concentration cell to measure Ksp for MCln. She constructs the cell by adding 2 mL of 0.05 M M(NO3)n to one compartment of the microwell plate. She then makes a solution of MCln by adding KCl to M(NO3)n. She adds 2.469 mL of the resulting mixture to a second compartment of the microwell plate.
Sally knows n (the charge on the metal ion) = +2
She has already calculated [Mn+] in the prepared MCln solution using the Nernst equation. [Mn+] = 8.035 M
How many moles of [Mn+] are dissolved in that compartment of the microwell plate? _____ mol
Provide your response to three digits after the decimal.

Question 3 1 pts Sally has constructed a concentration cell to measure Ksp for MCI, She constructs the cell by adding 2 mL of 0.05 M M(NO3), to one compartment of the microwell plate. She then makes a solution of MCI, by adding KCl to M(NO3). She adds 7.421 mL of the resulting mixture to a second compartment of the microwell plate. Sally knows n (the charge on the metal ion) = +2 She has already calculated [MT] in the...
A student does an experiment to determine the molar solubility of magnesium fluoride. She constructs a voltaic cell at 298 K consisting of a 0.766 M magnesium nitrate solution and a magnesium electrode in the cathode compartment, and a saturated magnesium fluoride solution and a magnesium electrode in the anode compartment. If the cell potential is measured to be 8.25x102 v, what is the value of Ksp for magnesium fluoride at 298 K based on this experiment? Ksp for MgF2-...
A electrolytic cell similar to that shown in the figure above is constructed. The electronic device shown at the top of the figure is a power supply. One electrode compartment consists of a manganese strip placed in a 1.0 M Mn(NO3)2 solution, and the other has a cobalt strip placed in a 0.5 M Co2(SO4)3 solution. The overall cell reaction is: 3 Mn2+(aq) + 2 Co(s) 3 Mn(s) + 2 Co3+(aq) (a) Fill in the information necessary to complete the...
Prelab Activity: Electrochemical Cells To determine the solubility product of copper(II) carbonate, CuCO3 , a concentration cell as described on pages 71-72 of the lab handout is constructed. The temperature of the Galvanic cell is measured to be 22.5°C, and the cell potential 282 mV (0.282 V). Using this data and Equation 8 in the lab manual, calculate the Ksp for CuCO3 and report your answer with three significant digits. For the Galvanic cell you will construct in PART B,...
Hi, can anyone please help me with this? i have no clue how to define if a reaction is Oxidation reduction or not. Thanks a lot OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
