As replacement of one ion of reactant takes place by another ion of reactant. Those reactions in which one element replaces another element from its salt or compound are called single displacement reactions. These are also called single replacement reactions. Generally, metals and their salts give single displacement reactions. In these reactions, more reactive metal displaces less reactive metal from its salt.

For example, potassium is more reactive than magnesium, so potassium replaces magnesium from magnesium chloride. Reactivity series is the series of metals based on their reactivity from highest to lowest. So, the reactivity series of metals can be defined as a series of metals, in order of reactivity from highest to lowest. It is also known as activity series. The reactivity of metals is because of their incomplete outer orbitals or due to their electronic configuration.

Metals form positively charged ions as they tend to lose electrons. Metals with high atomic numbers tend to be more reactive as their electrons are far from the positively charged nucleus. So, they can be removed easily.

Types of Chemical Reaction Synthesis Reactions Synthesis reactions happen when two separate atoms or molecules come together to generate a new molecule or substance. Discussion Oxidation-reduction reactions involve the transfer of electrons between substances.

The blue color of the aqueous copper II sulfate solution is due to the presence of the hexaaquacopper II ion in water. Materials 2 ea. This demo should be projected for large classes. To initiate the reaction, suspend the zinc strip by the glass rod so that it is immersed in the solution in one of the beakers. After two minutes have elapsed, pull the strip out of the beaker and show the class how the portion that was in the solution has darkened. Return to the demo several times during class to see how the reaction is proceeding.

By the end of class, the solution with the zinc strip in it should be considerably lighter in color. Use the beaker with no zinc in it as a control. By comparing the reaction solution with the control, the students can see that the reaction solution has become lighter in color. Safety Precautions Copper sulfate is moderately toxic. Handle with care.

Reserve the control solution for use the next time that demo is performed.

A lid can be made by cutting a suitably-sized piece from a polystyrene ceiling tile and making a hole for the thermometer. Provide a bowl or bucket for discarding the residues. Metal residues in sinks are almost impossible to remove. Iron particles rust and cause unsightly stains. Put the cup into a beaker so that it does not fall over.

Measure and record the temperature of the solution. Add the first of the powdered metals and stir the mixture with the thermometer. Observe the temperature over the next few minutes until a maximum temperature is reached. The solution is initially blue in color.

A dark coating of copper metal appears on the zinc within two minutes and when 45 minutes have elapsed, there is a thick coat of copper metal powder on the zinc strip and the blue color of the solution has lightened considerably. This demo can also be used when discussing single-replacement reactions, redox reactions, or electronegativity.

Active Learning Please consider not lecturing to your students. Use a series of well crafted questions, visualizations and a POGIL-ish tutorial to guide your students to understanding under what conditions single displacement reactions will occur. A set Power Point slides attempting to infuse some active learning in the presentation of this demonstration is posted on the menu to the right. Based on observations, write the the oxidation-reduction half-reactions. A new HTML5 based computer simulation of this activity is planned to be developed.
