Ions in their gas-like state are highly reactive and will rapidly interact with ions of opposite charge to give neutral molecules or ionic salts. Ions are also produced in the liquid or solid state when salts interact with solvents (for example, water) to produce solvated ions, which are more stable, for reasons involving a combination of energy and entropy changes as the ions move away from each o… Web1 mei 2024 · Ion channels are passive, or otherwise known as spontaneous, which allows the flow of ions to be transported across the a membrane based on when the signals are received. 1-2 The flow of the ions goes from the cytoplasm to the extracellular solution, and thus depolarizing the cell.
