- n. Plural form of half-cell.
Sorry, no etymologies found.
The margins of the notch present several half-cells which, when united with corresponding half-cells on the upper surface of the ethmoid, complete the ethmoidal air cells.
Soon the two half-cells thus formed separate from one another; and we now have four cells or an incipient quadrifid process.
When reduction or oxidation occurs, the metal ion in each part of the reaction is a half-cell, and these half-cells are connected by a salt bridge.
Usually when we need to determine the standard reduction potential of some half-cells, can use the standard reduction potential of reduction subtract the standard reduction potential of oxidation, which shows in this formula:
We cannot measure two separate half-cells, but we can measure the difference between them, which called the cell potential, by using this formula:
The emf's of the reduction and oxidation half-cells obviously combine to give the cell the greatest emf.
I’m still mystified at cell reproduction and how he came from the combination of two half-cells.
