An "Oxidised Element" is any element that has reacted with Oxygen to form a compound. The compound suffixes of these compounds will be "Oxide, Monoxide, Dioxide, Trioxide" etc. Some examples of oxidised elements:
Iron + Oxygen --> Iron Oxide
Carbon + Oxygen --> Carbon Dioxide
Magnesium + Oxygen --> Magnesium Oxide
Aluminium.
Which element will be oxidized and which will be reduced
In the given reaction, the hydrogen sulfide (H2S) is the element that gets oxidized. The sulfur in H2S changes from a -2 oxidation state to 0 in sulfur dioxide (SO2), indicating oxidation.
In the redox reaction between silver nitrate (AgNO3) and a reducing agent, silver (Ag) is oxidized. This occurs because silver loses electrons during the reaction, leading to its conversion from Ag+ in AgNO3 to elemental Ag. Thus, the element that has been oxidized in this reaction is the silver ion (Ag+).
Phosphorus
Aluminium.
When an element is oxidized, its oxidation number increases. Oxidation involves the loss of electrons, so the oxidation number becomes more positive in the process.
An element that increases its oxidation number in a reaction has been oxidized. This means it loses electrons or gains a more positive oxidation state. You can determine which element is oxidized by comparing the oxidation numbers of the element in the reactants and products of the reaction.
If an element has gained electrons, it has been reduced. If an element has lost electrons, it has been oxidized. This can be determined by comparing the oxidation state of the element before and after the reaction.
Oxidation means there's an increase in oxidation number. Reduction means there's a decrease in oxidation number.
The element has lost one or more electrons in a reaction.
Which element will be oxidized and which will be reduced
The material that is oxidized in the given reaction is Iron. Fe2O3 is iron oxide which can occur naturally as the mineral magnetite.
Al is oxidized because it loses electrons , O is reduced because it gains electrons.
iron is one anything that can be oxidized will rust
In the given reaction, the hydrogen sulfide (H2S) is the element that gets oxidized. The sulfur in H2S changes from a -2 oxidation state to 0 in sulfur dioxide (SO2), indicating oxidation.
Carbon
