Explanation: From the equation we see that Mg metal (oxidation state 0) changes to the ion Mg2+ . It is thus “oxidized” and is the reducing agent. ... It is thus “reduced” and is the oxidizing agent.
Is Mg2+ an oxidizing agent?
For this question, Cl2 and Mg2+ are already fully oxidized . You can't remove any more electrons since they already have a stable octet (not to mention chlorine is unstable under a positive charge unless it's bonded with an even more electronegative atom like fluorine).
Is mg reduced or oxidized?
The reducing agent in this reaction is the Mg as it will donate electrons to the silver ions . These are called ion-electron equations (or ionic half equations).
What is the oxidation state of MG s?
Magnesium is in group 2 so it will have an oxidation state of +2 . The compound has no overall charge so the oxidation state of sulphur must be -2.
Is mg oxidized?
When magnesium reacts with oxygen, the magnesium atoms donate electrons to O 2 molecules and thereby reduce the oxygen. Magnesium therefore acts as a reducing agent in this reaction. The O 2 molecules, on the other hand, gain electrons from magnesium atoms and thereby oxidize the magnesium.
Can oxygen be reduced or oxidized?
The oxygen atoms undergo reduction , formally gaining electrons, while the carbon atoms undergo oxidation, losing electrons. Thus oxygen is the oxidizing agent and carbon is the reducing agent in this reaction.
What happens when magnesium metal is oxidized?
where magnesium metal is oxidized and the dioxygen from the surrounding air is reduced resulting in a soft, white powder of magnesium oxide . At the level of atoms and molecules, a magnesium atom at the surface of the metal wire will meet a molecule of dioxygen.
How do you tell which is oxidized or reduced?
Oxidation numbers represent the potential charge of an atom in its ionic state. If an atom's oxidation number decreases in a reaction, it is reduced . If an atom's oxidation number increases, it is oxidized.
How do you know which reactant is oxidized?
If the oxidation number is greater in the product than the reactant, then the substance lost electrons and the substance was oxidized . If the oxidation number is less, then it gained electrons and the substance was reduced. The substance that is reduced in a reaction is the oxidizing agent because it gains electrons.
Is mg to mg2 oxidation or reduction?
For example, the synthesis of magnesium oxide, MgO , is a redox reaction in which oxygen gas oxidizes magnesium metal, while being reduced in the process. Each magnesium atom loses two electrons, so two magnesium atoms will lose a total of four electrons.
Which of the following is the strongest oxidizing agent?
Fluorine is thought to be the most powerful elemental oxidizing agent.
What is oxidation state?
Oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
What is the oxidation state of Mg in mg Oh?
Mg in Mg(OH)2 has +2 oxidation state. This shows that it has lost two of its electrons to make bond with OH- because it has gained two OH- ions which makes it loose 2 electrons and acquire +2 oxidation state.
How do you calculate oxidation states?
The oxidation number of a free element is always 0 . The oxidation number of a monatomic ion equals the charge of the ion. The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements. The oxidation number of O in compounds is usually -2, but it is -1 in peroxides.
How is oxidation number calculated?
The oxidation number of each atom can be calculated by subtracting the sum of lone pairs and electrons it gains from bonds from the number of valence electrons . Bonds between atoms of the same element (homonuclear bonds) are always divided equally.
