Identify the metals and their ions involved in the reaction from the problem statement.
Refer to the activity series of metals (Table 4.5) to determine the reactivity order of the metals involved.
Compare the reactivity of the metal in its elemental form with the metal in its ionic form. A metal will only displace another metal from its compound if it is higher in the activity series.
If the elemental metal is more reactive than the metal ion it is reacting with, predict that a displacement reaction will occur. Write the balanced chemical equation for the reaction.
If the elemental metal is less reactive than the metal ion, predict that no reaction will occur and write 'NR' (No Reaction).

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Activity Series of Metals

The activity series of metals is a list that ranks metals based on their reactivity, from most reactive to least reactive. It helps predict whether a metal will displace another metal in a chemical reaction. For example, a metal higher in the series can displace a metal lower in the series from its compound, while no reaction occurs if the reverse is true.

Single Replacement Reactions

Single replacement reactions occur when one element replaces another in a compound. This type of reaction can be predicted using the activity series; if the free element is more reactive than the element in the compound, a reaction will occur. If not, the result is no reaction (NR).

Single Displacement Reactions

Predicting Reaction Outcomes

To predict the outcome of a reaction using the activity series, one must compare the reactivity of the metals involved. If the metal attempting to displace another is higher in the series, the reaction will proceed, resulting in the formation of a new compound. If it is lower, the reaction will not occur, and NR is noted.
