activity series of metals lab answer key

We predict that Cl₂ should replace the I in KI, forming KCl and I₂. In this lab, the researchers found that magnesium is the most active metal and copper and aluminum are the least active metals. 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. We predict that Mg should replace the H in HCl, forming MgCl₂ and gaseous H₂.Īlso, Cu is above Ag.

Teacher notes are provided and an answer key. That activity series for metals compares the relative reactivity of metals by ranking them from most reactive to least reactive. A metal that displaces hydrogen gas from acid, but not from water, is less active than one that can displace hydrogen from both acids and water. A metal that displaces hydrogen gas from acid is more active than hydrogen. Students are required to qualitatively evaluate and compare the reactions to determine the order of reactivity. The relative activities of metals can be tabulated in an activity series, ranking the metals by relative ease of oxidation. This enables chemists to predict which combinations will undergo single displacement reactions.įor example, Mg is above H in the series. This lab activity uses real group 1 and 2 metals and shows the similarities and differences in physical properties and chemical properties. An element that is higher in the series will displace an element that is below it. Series, Resistance in Parallel and their Advantages/Disadvantages, What is. Metals are usually reclaimed from their ores in one of two ways: chemical reduction (using carbon in the form of coke) or electrolytic reduction (using electricity). PART AGB: REACTION WITH WATER List the metals in order of decreasing reactivity (. Chapter 3 Metals and Non-metals - What are Metals and Non-Metals, Physical. Compare your answer to question 3 with the activity series. This is the activity series which lists the most reactive metals on top and the least reactive on the bottom. Refer to table J in your reference table. List the 4 Metals in order from the most reactive to the least reactive. It lists the metals and nonmetals in decreasing order of chemical activity. You have completed the report, and it should be submitted to your instructor. Which of the metals reacted with the fewest solutions 3. 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. In this activity, students will run simulated tests of various metals in aqueous solutions to determine the relative reactivity of these metals. In a single-displacement reaction, one element displaces another element in a compound.
