Example of oxidation-reduction reaction?
ethanol can be oxidised to ethanal and further oxidised to ethanoic acid
What is oxidized in the reaction Mn HCl -- MnCl2 H2?
The way to tackle this to look at reactants and at the products, and this where oxidation numbers come in. Remembering that oxidation is loss of electrons and reduction is gain, (OILRIG is an acronym that is sometimes used). Mn metal is changed to Mn2+ so it is oxidised H in HCl has a +1 oxidation number and in H2 zero so it is reduced. Cl in HCL is at -1 and is -1 in MnCl2 so it is neither oxidised nor reduced.
What will happen when bromine reacts with sodium thiosulphate?
With 'sodium thiosulfate' (two words!) and bromine the reaction will be strong to give oxidised tetrathionate and reduced bromide: 2 S2O32−(aq) + Br2(aq) → S4O62−(aq) + 2 Br−(aq)
How can you tell if an element has been reduced?
The reactant that reduces another atom
What colour change will occur when potassium manganate VII reacts with iron II sulphate?
Mn(7+) is reduced to Mn(2+) going from purple to colourless/pale pink. The Fe(2+) ions are oxidised to Fe(3+) ions to complete the redox reaction.
Is the element zinc easily reduced?
No it is not. However, it is easily oxidised.
What is oxidized in H2 Cl2?
in the reaction of H2 and Cl2 hydrogen is oxidised. Chlorine is reduced.
Is a rusting car a redox reaction?
Yes, rusting is oxidation of iron. The iron is oxidised, the oxygen is reduced. This is thus basically a redox reaction.
Is 2Zn plus HCl equals ZnCl2 plus H2 a redox reaction?
yes as zinc is oxidised and hydrogen is reduced
What is the reaction between arsenic trioxide and iodine?
The arsenic iii ion is oxidised to arsenic V ion and iodine is reduced to iodide.
What does H2 do to N2 to make NH3?
It reacts with it. The reaction is a redx reaction. Nitrogen is reduced (its oxidation number goes from 0 to -3) and hydrogen is oxidised (its oxidation number goes from 0 to +1)
In the redox reaction AgNO3 Na NaNO3 Ag which element has been reduced?
Silver cations are reduced.
Example of oxidation-reduction reaction?
ethanol can be oxidised to ethanal and further oxidised to ethanoic acid
What is th oxidation number of phosphorus in red phosphorus?
Zero- red phosphorus is an allotrope of phosphorus, a form of the element. By definition elemnts are considered to be neither oxidised or reduced.
Is burning magnesium an oxidation-reduction reaction?
You cannot 'burn' MgO, it is refactory. I take it you mean burning Magnesium metal in oxygen - if so the answer is that the magnesium is oxidised to MgO and the oxygen is reduced - all reduction/oxidation ('redox') reactions are coupled - if something is oxidised the other is reduced.
What occurs to reducing agent in a reduction reaction?
An element is REDUCED. By that, it means that an element of a compound or an element in itself has gained electron/s when the reaction occurs. You can find this out when you see a change in their oxidation number.
What element is reduced in this reaction cr2o7 3hno2 5h-2cr3 3no3 4h2o?
Chromium
