What is the oxidising agent in kmno4 h2c2o4 h2so4?
In this reaction, potassium permanganate (KMnO4) acts as the oxidizing agent. It oxidizes oxalic acid (H2C2O4) to carbon dioxide and sulfuric acid (H2SO4) helps to provide the acidic conditions needed for the reaction to occur.
Are local anesthetic agents weak acid?
Yes, local anesthetic agents are weak bases, not weak acids. They work by blocking sodium channels in nerves, preventing the conduction of pain signals.
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
What are mild oxidizing agents?
Mild oxidizing agents are substances that can accept electrons from other molecules, causing them to be oxidized. Examples include hydrogen peroxide, ozone, and potassium permanganate. These agents are less reactive and less likely to cause vigorous reactions compared to strong oxidizing agents like nitric acid or chlorine.
Where can the oxidising symbol can be found around your home?
The oxidizing symbol can typically be found on household products like bleach, some cleaning agents, and pool chemicals. It is commonly displayed on the labels of these products to indicate their potential to generate oxygen or release oxygen during a chemical reaction.
What is obtained by oxidising 2-hexanone?
Ketones resist oxidation by most oxidising agents, including potassium dichromate and molecular oxygen.
Are ethanoic acid and sulfuric acid nonoxidising acids?
oxidising
What is the term for substances that promote oxidation?
An Oxidising agent.
What are the three agents of chemical weathering?
water,acids and air are all agents of chemical weathering

In this reaction, potassium permanganate (KMnO4) acts as the oxidizing agent. It oxidizes oxalic acid (H2C2O4) to carbon dioxide and sulfuric acid (H2SO4) helps to provide the acidic conditions needed for the reaction to occur.
What are oxidating agents?
those reagents which oxidize even very reactive compounds having weaker bond are called mild oxidising agents
Can janola harm you?
Yes, it contains strong oxidising agents and can easily damage skin if spilt on it, or your insides if swallowed.
Use of oxidizing agent in textile?
In textile industry oxidising agents are used to bleach cloths. Chlorine water is the example for this.
Are local anesthetic agents weak acid?
Yes, local anesthetic agents are weak bases, not weak acids. They work by blocking sodium channels in nerves, preventing the conduction of pain signals.
Why don't we make hydrogen when reacting an acid with copper?
Copper is unreactive and will not react with acids to liberate hydrogen gas. However it may react if concentrated and oxidising acids are used.
Why are oxidising agents dangerous?
Oxidising agents are dangerous because they can readily accept electrons from other substances, leading to rapid and often exothermic reactions. This property increases the risk of fire and explosion, especially when they come into contact with flammable materials or reducing agents. Additionally, their reactive nature can produce toxic byproducts, posing health hazards in various environments. Proper handling and storage are crucial to mitigate these risks.
Do all substanses need to be heated before oxidising?
No.
