Concept explainers
Interpretation: A galvanic cell and its working needs to be explained.
Concept introduction: A device which the free energy of a physical and chemical process is converted into electrical energy is known as galvanic cell. Such cell consists of two electrodes immersed in one or more suitable electrolytes.

Explanation of Solution
The structure of galvanic cell is as follows:
In this cell two electrons are immersed in the solution of two compartments. Two solutions are connected through a wire. At last two solutions are connected salt bridge. After the connection is made, current starts following as indicated by the ammeter. No current flows when the metal rods are disconnected or the salt bridge is taken out due to the reaction ceases.

- Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)arrow_forwardHi I need help on the question provided in the image.arrow_forwardDraw a reasonable mechanism for the following reaction:arrow_forward
- Draw the mechanism for the following reaction: CH3 CH3 Et-OH Et Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP.
