The oxidation number of Ni s 2. The metals from Table 2 were compared to each other in order to create an activity series. In some combinations, a reaction occurred, and in other combinations, a reaction did not occur. The activity series can be used to predict products of reactions, and to predict if a reaction will even occur.
Metals will give up electrons to become positively charged ions, called cations.
Metals higher on the activity series are more likely to reacts relative to those lower on the activity series. The oxidation number of Fe in the FeCl2 aq 3.
The chemical reactions for the preceding question B are: The oxidation number of Cl in the NiCl2 aq 7. When an atom loses its electrons, it is oxidized. Calcium was the most easily oxidized, while copper was least reactive. Introduction Reactions may or may not occur between two elements based on the activity series.
Then if you inserted the unknown piece of the metal into the solution of iron III chloride a deposit formed on the bottom of the well in the well plate. The oxidation number of Cl in the FeCl2 aq 4. Data from Table 2 was collected by obtaining a solution of metal ions and dropping in a piece of metal.
Solid metal was placed in a metal ion solution to determine if a reaction would occur. Where does the unknown metal fit into your activity series? Remember, sodium and copper are metals, too. The oxidation number of Ni in the NiCl2 aq 6.
The oxidation number of Fe s 5. Suppose you inserted a piece of an unknown metal into a solution of zinc II nitrate and observed no reaction. The element that is oxidized and the element that is reduced 8.
Where does nickel fit into your activity series? It was recorded if a reaction occurred or not, so that an activity series could be created.
Nonmetals will accept electrons to become negatively charged ions, called anions. For example, gas formations, bubbles, fizzy, or color change. In some cases, a reaction was observed.
When an atom gains electrons, it is reduced. Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction.
Metal reactions with HCl acid with observations and net ionic equations. List them in such a way that the most active metal is on the left and the least active metal is on the right.Oxidation-Reduction Activity Series Hands-On Labs, Inc.

A. Based on your observations make an activity series of the metals used. List them in such a way that the most active metal is on the left and the least active metal is on the right. Remember, sodium and copper are metals, too%(30). To keep track of electrons, it is convenient to write the oxidation and reduction reactions as half-reactions.
The half-reactions for Equation 1 are shown below. In this example, zinc loses two electrons and copper(II) accepts both. Title: Oxidation – Reduction Activity Series Documents Similar To Chem Lab Oxidation Reduction. Skip carousel.
