  • According to the electromotive series, zinc can reduce copper ions to metallic copper.

Examples

  • The electromotive series helps chemists predict the outcome of redox reactions.

  • The placement of lithium at the top of the electromotive series indicates its strong tendency to lose electrons.

  • The electromotive series helps predict chemical reactions.

  • Can you explain the electromotive series to me?

  • According to the electromotive series, potassium is more reactive than copper because it can easily reduce copper ions.

  • The electromotive series is essential for understanding the reactivity of different metals in chemical reactions.

  • A common application of the electromotive series is determining which metal can displace another in a solution.

Morphology

electromotive + series

The phrase is compositionally built from 'electromotive' (relating to electric generation/force) and 'series' (a sequence), so a learner can infer it denotes a sequence ordered by electromotive properties. However, the specific concept—ordering metals by standard electrode potentials and reduction tendencies—is technical domain knowledge that a B1 learner would not fully predict from the parts alone, so the term is only partly transparent.

Etymology

Electromotive series comes from its parts: electro (electric), motive (to move) and series (a list). Imagine metals in a line like runners: those near the top push electrons away and the ones below take them. That's why the series shows which metal will 'give' electrons and which will 'take' them in a reaction.
