Most plant-based foods, such as oatmeal and beans, contain both soluble and insoluble fiber. However, the amount of each type varies in different plant foods. To receive the greatest health benefit, eat a wide variety of high-fiber foods.
A galvanic cell is a device in which a spontaneous oxidation-reduction reaction is used to convert chemical energy into electrical energy. Galvanic cells harness the electrical energy available from the electron transfer in a redox reaction to perform useful electrical work.
Galvanic Cells, 2 Consider the galvanic cell pictured below, featuring two electrodes suspended in a solution of CdCl 2. One electrode is Cd, and the other is metallic Ag coated with solid AgCl.The net reaction is composed of a reduction and an oxidation, each of which is called a half-reaction.alvanic Cells, 4 To make a working cell, the reactants are separated into two half-cells which are connected with a salt bridge. The salt bridge is a U-shaped tube ï¬lled with a gel containing a high concentration of KNO 3 (or other electrolyte that does not affect the cell reaction).
