![]() ![]() ![]() In an activity series metals are arranged in order of decreasing ability to lose electrons. Will there be a reaction between Br₂ and KCl? Br is below Cl in the series, so we predict no reaction. An activity series is the ranking of metals according to their reactivity. The activity series is a list of elements in decreasing order of their reactivity. We predict that Cl₂ should replace the I in KI, forming KCl and I₂. We predict that Cu should replace the Ag in AgNO₃, forming Cu(NO₃)₂ and solid Ag.Ĭu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)Ĭl is above I. The top metals are more reactivethan the metals on the bottom. We predict that Mg should replace the H in HCl, forming MgCl₂ and gaseous H₂.Īlso, Cu is above Ag. The activity seriesis a chart of metals listed in order of declining relative reactivity. Associated particle diagrams will be displayed to help students better comprehend the reaction at the particulate level. Activity Series ( Read ) Chemistry CK-12 Foundation Activity Series Illustrates how to predict the outcome of reactions. This post will introduce the concept of metal activity series for Prelim Chemistry. In this simulation, students will reference an activity series and a solubility chart to accurately predict the products of single replacement and double replacement chemical reactions. This enables chemists to predict which combinations will undergo single displacement reactions.įor example, Mg is above H in the series. How Can We Order the Reactivity of Metals. An element that is higher in the series will displace an element that is below it. It lists the metals and nonmetals in decreasing order of chemical activity. It is the decreasing order of their reactivity. The general equation for a single-displacement reaction is:Ī and B must be either different metals (including H) or different halogens.Ĭhemists have devised an Activity Series. The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. Answer: Solution: Metals are arranged in activity series according to their tendency to lose valence electrons. In a single-displacement reaction, one element displaces another element in a compound. ![]()
