Oxidizing Definition and 24 Threads

The notes from MIT OCW I am reading contain the following ##E^\circ## denotes a standard electrode (aka redox) potential. Therefore, the quote above says that a positive ##E^\circ## means that relative to a standard hydrogen electrode, the electrode in question operates as a cathode, and the...

DiNitrogen is very unreactive due to the tripple bond it has, but what happens if it heated to very high temperature and bonds are broken? does it start behaving as a strong oxidiser. I could not find iinformation on at which temperature this happens but let's assume 3500K in a Tunston reactor...

why are they antibacterial, how they destroy bacterias? they just decompose organic molecules?

Hi, I have just concentrated some H2O2 from a diluted 3% concentration. I used it on a copper scrubbing pad earlier to test how well it would oxidize; but now there is a white, crusty substance where the H2O2 used to be. I then tested it on different surfaces, but every time it dries I get the...

Homework Statement How many moles of hydrogen peroxide will be oxidized by 0.0045 moles of potassium permanganate in acidic solution? I am unable to think of how you get started? Homework Equations [/B] n - m/mmThe Attempt at a Solution I've balanced the equation for an acidic solution...

I noticed on 1 of my stainless steel spoons that a film of Iron(II) oxide(which is a black rust) formed. I have been taught that stainless steel will not rust. So why would a stainless steel spoon be oxidizing?

Homework Statement Which substance is the oxidizing agent in this reaction? 2CuO + C = 2Cu + CO2 Homework Equations 2CuO + C = 2Cu + CO2 The Attempt at a Solution According to the online program I'm using for homework, CuO is the oxidizing agent, but I don't understand why. The oxidizing...

Homework Statement Identify the oxidizing agent and the reducing agent. 5Ag(s) + MnO4-(aq) + H+(aq) >>> 5Ag+(aq) + Mn2+(aq) + H2O(l) Homework Equations Increase of electrons is reduction caused by a reducing agent. Decrease of electrons is oxidation caused by an oxidizing agent. The...

Hi, I wonder if there is a material or paint/dye that would change color when exposed to air? Ideally, it should have the following properties: White-to-black, black-to-white, or any other high contrast color transition (e.g, yellow-to-brown would work too) Works under normal conditions...

Hello everyone, This may seem like a weird question, but today I had a discussion with my teacher in which I won't give up so easily. There was a test question that went like this: "A + 2 H+ + 2 e- ---> B Use this half-reaction to define whether A is a reducing agent or an oxidizing agent."...

I'm looking for some fast oxidizing materials that are cheap to deoxidize. For example: For my experiment I could use aluminum since it oxidizes very fast, but "aluminum oxide" is pretty expensive to turn back to aluminum as far as I know. What other material attracts oxygen and (oxidizes...

Hello people, so there is a gr.11 chem question that I've been struggling with... a) Identify three oxidizing agents (other than Fe2+) from the redox table that can also react as reducing agents. b)try to explain this suprising behavior. so, any ideas? i have a redox table in my textbook...

Homework Statement Sn(s)+NO3--->SnO2(s)+NO(g)Homework Equations The Attempt at a Solution 0 |+5 ,-2| |+4,-2| |+2,-2| Sn(s)+NO3--->SnO2(s)+NO(g) Sn lost 4e reducing agent N gain 3e oxidizing agent is that right? What about oxygen?? do...

My employer operates a biological water filtration plant. The first stage of filtration has the raw water passing through a filter embedded with bacteria, the processes used here is aerated biological treatment where oxidizing processes (bio-oxidation) are used and the microbes gain energy when...

Hi there, I have some trouble understanding redox reactions. Here is the question: Sulphuric acid is one of the strongest inorganic acides which in some reaction shows oxidation properties. In which of reactions below, sulphuric acid acts as oxidating tool? A. \text{H}_2{SO}_4 +...

I would be glad if someone compiled a list or atleast provide the link for the actions of various oxidizing and reducing agents like LAH, BAH, hydrogen, potassium permanganate etc. and on the various functional groups. This will be very useful to any organic aficionado and I will be very happy...

okay, so here's another question: the reaction for G-3-P oxidizing to 1,3-BPG is: G-3-P + NAD+ + Pi --> 1,3-BPG + NADH + H+. I understand that the hydride ion leaves G-3-P and donates two electrons and one proton, which neutralizes the charge on NAD+ and gives NADH. But it is only giving one...

I was wondering how much stronger potassium chlorate is vs. potassium nitrate in oxidizing power, and how to look up the information for myself next time if possible. Thanks :smile:

Is it possible to cheat a fuel-cell based breathalyzer with oxidizing gases like nitrous oxide? (For a brief explanation on how these types of breathalyzer works, see http://science.howstuffworks.com/breathalyzer5.htm )

When a metal displaces hydrogen from a non-oxidizing strong acid, which substance is the oxidizing agent? Thanks :smile:

I need to find the best oxidizing and reducing agent in the periodic table and say why i chose what i chose. I think the best oxidizing agent is Fluorine and the best reducing agent is Lithium I am not sure if my predictions are correct and if they are I don't know how to explain why I...

Hi. I have this problem I've been trying for a week and i still can't figure it out: 1. A reacts spontaneously with 1 mol/l BNO3, 1 mol/L D(N03)2 and dilute sulfuric acid. A does not react with 1 mol/L C(N03)2. 2. B does not react spontaneously with any of the the 1 mol/L solutions aove...

What part of the periodic table contains elements which behave as strong oxidizing agents?

What are the benefits of oxidizing gold? I suppose that prevents it from rusting, but are there any other benefits?
