[whats-in-a-sentence]

Figure 12.15a illustrates the hydrogen electrode connected to a copper half-cell to form a galvanic cell. (...) Now let's look at a galvanic cell set-up between a zinc electrode and a hydrogen electrode (see figure 12.15b).

[whats-in-a-sentence]

For example, a galvanic cell can be made using an anodic half-cell composed of a zinc electrode dipping into a solution containing Zn²+ and a cathodic half-cell composed of an inert (nonreacting) platinum electrode dipping into a solution both Fe²+ and Fe³+ (figure 12.13).

[whats-in-a-sentence]

Instead, if a zinc rod (electrode) is dipped into a solution of ZnSO4 and a copper rod (electrode) is dipped into a solution of CuSO4, and the solutions are connected with a salt bridge (its function will be explained shortly), zinc can transfer its electrons to the copper ions only through an external circuit (see figure 12.10a). (...) When a copper electrode in a solution of Cu(NO3)2 is connected to a silver electrode in a solution of AgNO3, the current flows in the opposite direction (see figure 12.10b). (...) The salt bridge shown in figure 12.10 allows the movement of ions required to keep the solutions neutral. (...) As mentioned before, the standard cell potential for the galvanic cell constructed from silver and copper electrodes shown in figure 10.12b is only 0.46 V.

[tenth-sentence]

In a galvanic cell, the 'electron gas' flows from the electrode with the higher 'electron pressure' (zinc) to the electrode with the lower 'electron pressure' (copper), which is indicated by the direction of the arrow above the voltmeter in figure 12.10a.

heroes in a half shell???

NAH

Hero with a HALF CELL BABEY!!

I CALL THAT SHIT GALVANIC

I actually made a few cells. Here’s the second
