Hydrogen bubbles form in the cathode while zinc metal increases in mass in the anode. b. The cathode solution becomes acidic due to hydrogen ions while zinc metal dissolves in the anode. c. Zinc metal increases in mass in the cathode while the anode solution becomes acidic due to hydrogen ions. d. Hydrogen bubbles form in the cathode while zinc metal dissolves in the anode.

How is the amount of current flowing through an electrolytic cell related to the amount of product produced in the redox reaction? Match the items in the left column to the appropriate blanks in the sentences on the right. multiplied coulombs Avogadro's 1 mol Faraday's 1g ampers 6.022 x 10¹ mol volts divided The number of moles of electrons that have flowed in a given electrolysis cell can be determined by measuring the total charge that has flowed through the cell. If the amount of current flowing through the cell is by the time that the current flowed, the total charge that passed through the cell in that time can be found. The relationship between charge and the number of moles of electrons constant, which corresponds to the charge in is given by of of electrons. These relationships are used to solve problems involving the stoichiometry of electrolytic cells. Reset Help

11- An electrolytic cell is set up using inert electrodes in an aqueous copper(II) sulfate solution. After an hour of electrolysis, the solution is tested. The concentration of copper(II) ions has decreased, while the concentration of hydrogen ions has increased. The mass of one electrode has also increased. Explain these observations using the half-reaction equation for each electrode.

What statement is true for a galvanic cell?   a. Electrons move from the reduction to the oxidation half-reaction.   b. The salt bridge is used to transport electrons.   c. Oxidation takes place at the anode.   d. The standard cell potential is negative.
