有关原电池、电解池的应用和原理是高中化学的一个重点内容。过去在一些不同的课本和书刊中,原电池和电解池的电极名称不一致,容易发生混淆。本文试图从有关命名的规定原则加以说明,并将原电池和电解池的电极名称、电极反应、电子流向等作一系统的分析、对比。命名原则.原电池和电解池都跟电流有关,同时都跟电极发生的化学反应有关,因而原电池和电解池的命名原则就有两种。
The applications and principles of primary batteries and electrolytic cells are a key part of high school chemistry. In the past, in some different textbooks and books, the electrode names of primary batteries and electrolytic cells were inconsistent and prone to confusion. This article tries to explain the principle of naming, and analyzes and compares the names of the electrodes of the galvanic cells and the electrolytic cell, the electrode reactions, and the electron flow. Nomenclature: Primary cells and electrolysis cells are all related to the current and are related to the chemical reactions occurring at the electrodes. Therefore, there are two naming principles for primary cells and electrolytic cells.
