The last four metals in the activity series of metals are commonly referred to as the coinage metals. In the first reaction we determined that zinc is more active than copper and the third reaction shows us that zinc is also more active than tin. Use the activity series for metals to explain why copper metal is used in plumbing where the water might contain compounds of many different metals. positions of the metals in the reactivity series, would a reaction occur between Mg()s and AlCl()3aq if the. Using all three of the reactions above, we can make an activity series for Cu, Zn, and Tin. Displacement reaction of metals worksheet. G-inorganic-05-05, Reactivity series of metals, Information. If a piece of zinc is placed in the SnCl 2 a reaction occurs. Worksheets and practical guides to support GCSE inorganic chemistry, and pages that describe. Typically, in order to determine the reactivity series. Conversely, at the bottom end of the series, you would find the least reactive. At the top end of the scale, chemists and scientists will place the most reactive of the metals contained in the series. In this case the tin is more active than the copper, as the copper is not able to force its electrons onto the tin. A reactivity series, also known as an activity series, is a way of categorising metals. Tie-ins include single-replacement reactions (SRR), oxidation-reduction, practical applications such as galvanization, and predicting reactions. Suppose a piece of copper was placed in a solution of SnCl 2, and nothing happens. Overview: The students will develop their own activity series of metals based on lab results. When an ion keeps the same charge in a reaction and is just there to balance out the opposite charges, we call it a Spectator Ion. In this way, a series of Ln 1 PtHCS catalysts (here Ln Ce, Pr, Nd, and Lu) should all possess enhanced HOR catalytic activities due to the high oxophilicity of Ln metals. Nitrate ion in both the reactants and the products has a -1 charge. In the equation below, nitrate is there to balance the charges. Positive ions (cations) can't just be floating around by themselves in solution, they have to have a negative ion (anion) to balance them. We say that Zn is more active than the copper. \): An activity series for common metals.Įxample: Zn and Cu both tend to lose 2 electrons, but the zinc wants to lose them more, so much so that it can force the two electrons on Cu 2 + and make it become Cu again. In this activity, students will run simulated tests of various metals in aqueous solutions to determine the relative reactivity of these metals.
