Course Home Course Home 9 My Home My Home OWLv2 Online teach -6, 7.6-7.7 Review [References] 1 1 pt 2 1 pt A common experiment to determine the relative reactivity of metallic elements is to place a pure sample of one metallic element into an aqueous solution of a compound of another metallic element. If the pure metal you are adding is more reactive than the metallic element in the compound, then the pure metal will replace the metallic element in the compound. For example, if you place a piece of pure chromium metal into a solution of copper(II) sulfate, chromium will slowly dissolve to produce chromium(III) sulfate solution, and the copper(II)ion of the copper(II) sulfate will be converted to metallic copper. Choose the unbalanced equation for this process.
