Is Fe2+ a reducing agent?
Fe2+ will readily oxidise( it easily lose an electron) to gain stable configuration of 3d5 whereas Cr2+ will not oxidise so readily as the resultant configuration 3d3 is not that stable. Hence Fe2+ act as stronger reducing agent ( gets easily oxidised by losing electron).
How do you know which is the strongest reducing agent?
The reducing agent is stronger when it has a more negative reduction potential and weaker when it has a more positive reduction potential. The more positive the reduction potential the greater the species’ affinity for electrons and tendency to be reduced (that is, to receive electrons).
Is Fe3+ reduced or oxidized?
The pale green Fe2+ is oxidised to orange Fe3+ because it loses an electron. This is an oxidation reaction because there is a loss of electrons and an increase in oxidation number.
Which type of chemical reaction takes place in conversion of Fe2+ into Fe3+?
An oxidation/reduction reaction is one in which electrons are transferred from one reactant to another. An example is the oxidation of iron(II) ions by cerium(IV) ions: Ce4+ + Fe2+ ⇌ Ce3+ + Fe3+ Here, Ce4+ ion extracts an electron from Fe2+ to form Ce3+ and Fe3+ ions.
Is Fe2+ and Cr3+ A stronger reducing agent?
The highest oxidation state for Cr is +6, therefore it can loose 3 more electrons, whereas Fe needs to loose only 1 electron to achieve its highest oxidation state of +3. Thus, Cr3+ is more reducing than Fe2+.
Why Cr2+ is stronger reducing than Fe2+?
Cr2+ is a stronger reducing agent because it can lose one of its electron to become Cr3+ in which the t2g level of d-orbital is half filled and eg level is empty.
Which is a stronger reducing agent Cr3+ or Fe2+ and why?
Is HNO3 a reducing agent?
No, nitric acid is a powerful oxidising agent. In nitric acid (HNO3), nitrogen is in its maximum oxidation state of +5, and it cannot be oxidised further to any higher state. So, it cannot act as a reducing agent.
What is the standard reduction potential for Fe3+ to Fe given that?
The Activity Series
| Reduction Half-Reaction | Standard Reduction Potential (V) |
|---|---|
| Ag+(aq)+e- → Ag(s) | +0.80 |
| Fe3+(aq)+e- → Fe2+(aq) | +0.77 |
| I2(l) + 2e- → 2I-(aq) | +0.54 |
| Cu2+(aq)+2e- → Cu(s) | +0.34 |
How do you convert Fe2+ to Fe?
The loss of negative charge causes an increase in oxidation state of the substance. Fe atoms lose two electrons, so they are oxidized to Fe2+ ions. Note that the two-electron oxidation raises the oxidation state of iron from 0 in the atom to +2 in the ion.
Which substance can be used to convert Fe2+ ions to Fe3+ ions?
Example: Acidified manganate(VII) ions are a powerful oxidizing agent. They can oxidize Fe2+ ions to Fe3+ ions.
Which is a stronger reducing agent CR 2 + or Fe 2 + and why?
Which is a stronger reducing agent Cr 2+ or Fe 2+ and why? reducing agent means it will reduce the other & itself gets oxidized. Means, one which will have a greater tendency to lose e ⊖, would be better reducing agent.
Which is the reducing agent in the redox reaction?
In the redox reaction: Cr2O72- + Fe2+ –> Cr3+ + Fe3+. What would the balanced reaction look like, and would CrO72- be the Reducing Agent, and Fe2+ be the Oxidizing Agent? Dichromate is the oxidizing agent….
Which is the stronger reducing agent cu or Zn?
This is actually a very common reaction in students labs: all you need is an aqueous solution of Cu (II) and metallic Zn: Cu²⁺ oxidises Zn to Zn²⁺ while getting oxidised itself to Cu²⁺. The reverse reaction will not happen spontaneously. In other words, the stronger reducing agent is Zn because it gets oxidised to Zn (II) by Cu (II).
