What is the relationship between oxidizing and oxidizing agent?
An oxidizing agent is a substance that causes another substance to be oxidized. Oxidation refers to the loss of electrons by a substance, while reduction refers to the gain of electrons. In a redox reaction, the oxidizing agent itself gets reduced as it accepts electrons from the substance being oxidized.
What substance in blood reacted with hydrogen peroxide?
The iron in haemoglobin is reduced oxidised by the hydrogen peroxide which is an oxidising agent.
What role play oxidising agent in a reaction?
An oxidizing agent causes oxidation by accepting electrons from the substance being oxidized. It facilitates the loss of electrons from one substance, which leads to the oxidation of that substance. In the process, the oxidizing agent itself is reduced.
What is used to test for reducing and oxidising agents?
When some substances are oxidised or reduced, there is a colour change.Testing for a reducing agent:An oxidising agent is a substance that causes another substance to be oxidised & is itself reduced. Acidified potassium manganate (VII) is an example of one. While it oxidises other substances, the manganate ion is reduced (because the oxidation state decreases showing that reduction is occuring) :MnO4- --> Mn2+oxdations state:+VII+2colour:PinkColourlessSo, to see if an unknown substance is a reducing agent, add acidifies potassium manganate (VII) to see if the pink colour fades. If it does, you know the unknown substance was a reducing agent, because it caused reduction.Testing for an oxidising agent:A reducing agent is a substance which causes reduction, but is oxidised itself. Potassium iodide is a powerful reducing agent. While it reduces other substances, the iodide ion is oxidised (because the oxidising state increases) resulting in a colour change:2I- -->I2Oxidising state:-10 (the oxidising state of a diatomic molecule is 0)Colour:ColourlessRed-brownSo, to see if an unknown substance is an oxidising agent, add potassium iodide to see if a red-brown colour appears. If it does, you know your unknown substance is an oxidising agent because it caused a reduction
A substance that shows a decrease in oxidation number during chemical reaction?
A substance that shows a decrease in oxidation number during a chemical reaction is being reduced. Reduction involves a decrease in the oxidation number of an element. This indicates a gain of electrons by the substance.
Why a substance that oxidised is called a reducing agent and why a substance that is reduced is called an oxidising agent?
It is because when a substance is oxidized, it loses electrons which are taken up by other so that is gets reduced.This is why it is called reducing agent. Similarly, the substance reduced is called oxidizing agent.
What is the relationship between the speed of an electromagnetic waves and density of a substance?
The speed of electromagnetic waves in a substance is inversely related to the substance's density. In denser materials, electromagnetic waves travel slower compared to less dense materials. This relationship is described by the material's refractive index, which quantifies how much the speed of light is reduced when traveling through a medium.
What is the name for a substance that gains an electron or loses oxygen?
This substance is called an Oxidant or an Oxidising Agent .It oxidises the other substance and reduces itself .
When a substances gains electrons is it reduced?
Yes when any substance gains electrons , that substance is now then reduced.
A substance that can not be reduced to a simpler substance by chemical means?
An "element"
The substance that accepts electrons from another substance is the?
In a redox reaction, the substance that accepts electrons is said to be the substance reduced. This substance is also likely the oxidizing agent, since oxidation is the loss of electrons.
What happens in a redox reaction?
Electrons are transferred between atoms.
