Four voltaic cells are set up. In each, one half-cell contains a standard hydrogen electrode (SHE). The second half-cell i 2+ . Cr (aq, 1.0 м) | Cr(s) 3+ . АГ" (аg, 1.0 M) | AI(s) 2+ . Са (ад, 1.0 M) | Ca(s)

Prepare a sketch and write the half-reactions and overall cell reaction for the electrochemical cell designated by:       Pt(s) | Ag(s) |AgCl(s) | Cl-(a = 1) | Cl2(g, 1 bar)| C(graphite) | Pt(s)

The cell notation of a voltaic cell is: Zn(s) | Zn2+(aq; 0.02M) || Zn2+(aq; 1.0 M) | Zn (s) Draw a diagram of the cell and each half-reaction. Label the anode, cathode, and each relevant reaction. What is Eocell at equilibrium? Why? What is the expected Ecell at T = 273K? Given this Ecell, will the Q of this cell increase or decrease to reach equilibrium?

Enter electrons as e A voltaic cell is constructed in which the anode is a Fe2+|Fe3+ half cell and the cathode is a F|F, half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: The cathode reaction is: The net cell reaction is: +. In the external circuit, electrons migrate the Fe2+|Fe3+ electrode the F|F, electrode. from to In the salt bridge, anions migrate the F|F, compartment 3- the Fe2+|Fe+ compartment. +. +. 1

Consider the voltaic cell {Cu(s)|Cu2+(aq. 0.89 M)||Ag+(aq, 0.48 M)|Ag(s)}. What is E0cell and Ecell for this cell at 25 C?
