Question

some questions are filled out but still need help woth the remainder of this assignment

Paragraph Styles . . Electrochemical Cells Objective: Investigate electrochemical potential using electrochemical cells. Information: Electric current is the flow of negatively charged particles. An electrochemical cell is a device that creates an electric current by converting chemical energy into electric current, or vice versa. Voltaic cells are electrochemical cells that produce current spontaneously by converting chemical energy into electrical energy via an oxidation-reduction reaction. By creating an electric potential between an "anode" and "cathode", electrons are forced to move from the anode to the cathode. The current will spontaneously flow from the anode to the cathode in a Voltaic cell. The force that moves the electrons in a Voltaic cell depends on many variables such as type of anode, type of cathode, temperature, external pressure, etc. The force is historically termed the "electromotive force", but the true form of the force is as an electric potential. The electric potential can be measured quantitatively by use of a voltmeter. A car battery is a Voltaic cell. It changes chemical energy into electrical energy. Batteries need three parts: a cathode (positive electrode), an anode (negative electrode), and an electrolyte (material to transfer electrons). The electrolyte material is most often referred to as the "salt bridge". Procedure: Part A: Standard cells Go to the following website and follow the instructions below: https://pages.woregon.edu/tgreenbo/voltaicCellEME.html (I found that internet explorer works best, but you may have to try different browsers) 1. Set up a series of voltaic cells with each half-reaction listed in the table below using a 1 M concentration of the appropriate solution (is the half reaction for Ag (s) should also contain AgNO.). Record all voltages. In addition record the direction that the electrons are moving in the wire. Half-reaction 1 Half-reaction 2 Voltaren Cathode Direction Anode
