whats the products of the aquaeus electrolysis of Cu(NO3)2
How many grams of Pb_ would be deposited by the electrolysis of a PbSO_4 solution at 3.2 amps for 2 hours?
Cu(OH)2 can be obtained from the addition of excess NaOH solution to a solution of Cu(NO3)2 as shown in the figure. If the NaOH is added to 35.0 mL of 0.167 M Cu(NO3)2 and the precipitate isolated by filtration, what is the theoretical yield of Cu(OH)2? Cu(NO3)2 (aq) + 2 NaOH (aq) → Cu(OH)2 (s) + 2 NaNO3(aq) 0.4718 5858 1.10 g 0.570 g 1.14g
A current of 3.43 A3.43 A is passed through a Cu(NO3)2Cu(NO3)2 solution for 1.60 h1.60 h. How much copper is plated out of the solution?
a. For the electrolysis of molten BaCl2, diagram a cell. Include the direction in which a battery would be placed to power the cell. Write out half-reactions. Label flow of electrons, anode, cathode, indicate what is formed at each electrode (assume electrodes are generic metal). Could this reaction be carried out in aqueous solution? Why or why not (justify numerically). b. 0.67 g of Ag is deposited electrolytically from AgNO3after a certain period of time when subjected to a 12A...
A mixture of Cu(NO3)2 and Cu(NO3)2.2.5H20 has a mass of 3.150 g. Upon heating the water is driven off and the mass of the Cu(NO3)2 is 2.853 g. Determine the % by weight of the Cu(NO3)2.2.5H20 in the original mixture.
