![]() ![]() ![]() Pay attention to the notes below as they are provided to help you make better use of the activity series than just the list of metals by themselves. It also can be used as an aid in predicting products of some other reactions. We could also predict that aluminum will displace mercury from solution by the following reaction.Ģ Al(s) + 3 Hg(NO 3) 2(aq) 3 Hg(l) + 2 Al(NO 3) 3(aq)Ģ Al(s) + 3 Hg +2(aq) 3 Hg(l) + 2 Al +3(aq)Ĭontinue on and read about how we set up an activity series. The Activity Series of the metals is an invaluable aid to predicting the products of replacement reactions. Metals from Li to Na will replace H from acid and water Metals from Mg to Pb will replace H from acids only. Step 1 - Write the formulas of the reactants on the left of the yield sign. However, it will displace H + from an acid by the following single displacement reaction.Ģ Al(s) + 6 HCl(aq) 3 H 2(g) + 2 AlCl 3(aq)Ģ Al(s) + 6 H +(aq) 3 H 2(g) + 2 Al +3(aq) ACTIVITY SERIES REFERENCE CHART In general, a metal can displace any of the metals which are lower in the reactivity series. Worksheet 4: Single-Replacement Reactions. ![]() In a solution or compound, an elemental metal will displace any metal lower than it on the activity series.įrom the activity series above, we can predict that aluminum will not displace H from water. Organizing the metals in this fashion also allows us to predict how the metals will react with each other. Reactivity Series KS3 - Worksheet Put the following metals in order of reactivity. The least reactive metals are not able to displace hydrogen from either of these and are therefore found at the bottom of the series. You will then use the results of your tests to construct a scale of relative reactivities of the metals. (c) metal 'C' which is kept in the middle of activity series. Only a few of the most reactive metals are able to displace hydrogen from water while a larger number will displace H + from an acid. In this experiment, you will test the reactivities of a variety of metals with different metal ions. Which of the following lines in the periodic table separates metals from. This means that in a metal activity series we would find the most reactive metals at the top. Activity Series of Metals Introduction: Would a car made of gold rust as fast as a car made of iron or aluminum Silver tarnishes by reaction with sulfur in the atmosphere to form black silver sulfide. Potassium is higher in the activity series. Once organized, an activity series helps us to predict if a reaction will occur when a piece of elemental metal is placed in water, an acid solution, or a solution containing the ion of another metal.Īctivity series are generally listed in order of decreasing reactivity. The relative reactivity of metals can be used to organize them into an activity series. ![]()
