Definition: Describes something that has undergone a chemical reaction with oxygen, often resulting in a change in color or composition.

Example: The metal has oxidised, giving it a rusty appearance.

Definition: To have undergone a chemical reaction with oxygen, often resulting in a change in color or composition.

Example: The metal has oxidised, causing it to turn a reddish-brown color.

Definition: A substance that can cause or promote the combustion of another material by providing oxygen or another oxidizing agent.

Example: In the laboratory, we used an oxidiser to enhance the reaction between the chemicals.

Definition: Relating to a process that involves the addition of oxygen to a substance or the removal of hydrogen from it, often resulting in a chemical change.

Example: The oxidising agent in the reaction helped to convert the metal into its oxide form.

Definition: To combine with oxygen or to cause a substance to combine with oxygen, often resulting in a change in chemical composition.

Example: The process of oxidising iron leads to the formation of rust.

Definition: Able to undergo a chemical reaction where a substance combines with oxygen or loses electrons.

Example: Iron is oxidizable, which is why it rusts when exposed to moisture and air.

Definition: To undergo a chemical reaction in which a substance combines with oxygen, often resulting in a change in its properties.

Example: Iron will oxidize when exposed to moisture and air, leading to rust.

Definition: To combine a substance with oxygen, often resulting in a chemical change.

Example: When iron is exposed to moisture, it can oxidize and form rust.

Definition: A material that helps another substance to burn by providing oxygen or by removing electrons from it.

Example: Hydrogen peroxide is a common oxidizer used in various chemical reactions.

Definition: A type of enzyme that helps speed up chemical reactions involving the transfer of electrons between molecules, which is important for processes like metabolism.

Example: The oxidoreductase plays a crucial role in cellular respiration by facilitating the transfer of electrons.

Definition: A type of chemical compound that is created when aldehydes or ketones react with hydroxylamine, characterized by the presence of a specific functional group.

Example: The chemist synthesized an oxime from the aldehyde to study its properties.

Definition: A device that measures how much oxygen is in the blood.

Example: The doctor used an oximeter to check the patient's oxygen levels.

Definition: The process of measuring how much oxygen is in the blood, especially in the arteries.

Example: Doctors use oximetry to check the oxygen levels in patients' blood.
