Measure room temperature and record: Soak a steel wool pad in 30 mL of vinegar in a mL beaker. Remove pad and squeeze the excess vinegar back into the beaker.
Fluorine and oxygen are known to be the strongest oxidizers because they rip electrons off of other elements. After they take the electrons, they become ions left column which are quite inactive. By the way, you will be doing this later as an experiment.
Combined it looks like the reaction below.
In all of these reactions, one is the oxidizer and the other is the reducer. It all depends on who is giving and who is receiving the electrons.
As another example, this chart shows that mercury metal will give its two valence outer electrons to oxygen gas. The mercury ion and oxide ions then bond together for form solid mercury II oxide, HgO. We also said that magnesium would work.
If you look at the chart, magnesium is higher on the chart than the silver. That means magnesium is more active in giving its electrons away compared to silver. So magnesium will work. Even hydrogen gas would work. Lead and iron would probably be the cheapest metals to use.
Again, the more reactive elements mostly metals here will give their electrons to the less reactive metal ions. Note, that magnesium is higher than zinc, but magnesium will not give its electrons to zinc, only to zinc ions.
Zinc metal atoms can't accept any electrons. Also note that the positive metal ions in the right column can't give any electrons.
They have already lost their electrons. So passing along of electrons starts in the left column and is handed to anything listed in the right column that is below the element in the left column. All elements can be a reducer if it has an element below it in the chart. In other words, it can reduce the positive charge on the element below it.
The most active reducers are the ones at the top of the chart in the left column. Lithium being the strongest.

Anything in the right column can be an oxidizer if it has an element above it. It oxidizes the element in the left column above it by pulling off and accepting the other elements electrons.
The elements at the bottom of the right column are the most reactive oxidizers. Fluorine gas is the strongest listed. If you put the strongest oxidizer F2 with the strongest reducer lithium metalthe reaction will be violent. When there is a tendency for one thing to push its electrons over to something else that wants those electrons, then there is an electrical voltage.
Hydrogen is set as zero volts. Lithium has the highest negative voltage because it will build up an the highest excess of electrons as it tries to give them to hydrogen ions.
So a measurement of voltage is giving an indication that electrons are wanting to travel from a metal to the ions of a different metal. Again, a voltage will only occur if the metal is in a row higher than the metal ion. It doesn't always have to be a metal ion.
At the bottom of the chart are some non-metals.
Single Replacement Reactions. Lab Report. PURPOSE: To investigate the reactivity of different metals in single-replacement reactions. QUESTION: THE PROJECT: To design an experiment that will determine which of the metals: Write balanced and chemical equations of all the reactions you tried. Single replacement reactions are reactions in which an element in pure form competes for a place with an ion or atom in a compound. One type of single replacement reaction is the replacement of hydrogen in acids by active metals, producing. Typically, you will be given the left-hand (reactant side) and asked to provide the products to the reaction. You need to be able to recognize single replacement reactions AND be able to break a formula apart into proper cations and anions as well as write correct formulas.
That combination is better at ripping electrons off of other elements than either one by itself. In this lab, you will be using a multimeter set to measure voltage to measure this voltage that these metals and ions can create.

QUESTION: THE PROJECT: To design an experiment that will determine which of the metals: Write balanced and chemical equations of all the reactions you tried. Predicting Products and Writing Equations Strand Nomenclature, Chemical Formulas, In a single replacement reaction, a single uncombined element replaces another in a compound.
efore undertaking these lab experiments, be sure your school’s chemical hygiene plan allows for the use of the chemicals required. In this lab you will be performing several experiments. For each one you will be expected to write an equation and indicate the type of reaction (composition, decomposition, single replacement, or double replacement).
