A cell needs to take up Na+ ions. The concentration of Na+ outside the cell is 200 ppm, and inside the cell it is 350 ppm. Which type of transport will the cell use?
What makes this an oxidation-reaction? 3Ag2S+2Al(s) -> Al2S3+6 Ag(s)? Write the half-reactions showing the oxidation and reduction reactions. Identify which is the oxidation reaction and which is the reduction reason. What is oxidized in the reaction? What
In lab, we did an experiment with electrochemical cells with solutions of ZnSO4, CuSO4, Al2(SO4)3 and MgSO4 and their respective metal electrodes. There are a couple of post-lab questions that I'm not sure about: (1) Summarize Part A with a data table
A voltaic cell is constructed that uses the following half-cell reactions. Cu+(aq) + e- Cu(s) I2(s) + 2 e- 2 I -(aq) The cell is operated at 298 K with [Cu+ ] = 2.3 M and [I - ] = 3.3 M. (a) Determine E for the cell at these concentrations. (b) If [Cu+ ]
1) Assume that the reference half-cell is changed to a standard mercury-mercury (II) half-cell. a) What would be the reduction potential of a standard chlorine half-cell. c) What would be the cell potential of a standard chlorine-nickel cell. 2) For each
Compare hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens to the cell?1pt a.The cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell. b.The environment has more
