A reducing agent (also called a reductant, reducer, or electron donor) is an element or compound that loses or “donates” an electron to an electron recipient (called the oxidizing agent, oxidant, or oxidizer) in a redox chemical reaction.
What is reducing agent with example?
A reducing agent is typically in one of its lower possible oxidation states, and is known as the electron donor. A reducing agent is oxidized, because it loses electrons in the redox reaction. Examples of reducing agents include the earth metals, formic acid, and sulfite compounds.
Which is best reducing agent?
– Lithium is the strongest reduction agent because it has the smallest standard reduction potential. It decreases the charge on another species and itself oxidizes. It is one of the powerful reducing agents. It is smaller in size and loses electrons easily.
Which substance is a reducing agent?
| Oxidizing Agents Reducing Agents | Substance is... Reduced Oxidized |

Is Cl2 a reducing agent?
To help eliminate confusion, here is a mnemonic device to help you remember how to determine oxidizing and reducing agents. Br− loses an electron; it is being oxidized from Br− to Br2, thus Br− is the reducing agent. Cl2 gains one electron; it is being reduced from Cl2 to 2 Cl−, thus Cl2 is the oxidizing agent .
What is a reducing agent simple definition?
: a substance that reduces a chemical compound usually by donating electrons .
Is kmno4 a reducing agent?
Potassium permanganate, KMnO 4 , is a powerful oxidizing agent , and has many uses in organic chemistry.
Is Aluminium a reducing agent?
Aluminium is used as a reducing agent in the extraction of metals in those cases where the metal oxide is of a comparatively more reactive metal than zinc etc,. which cannot be satisfactorily reduced by carbon.
Which is the weakest reducing agent?
Coke has a negative standard electrode potential. Whereas, hydrogen gas has zero electrode potential. This value is greater than the other negative values. Therefore, hydrogen gas has the highest electrode potential, so it is the best oxidising agent or we can say that weakest reducing agent.
Is chlorine a reducing agent?
Chlorine is an oxidising agent since it needs one electron in its valence shell to occupy the one empty space. Chlorine is capable of taking electrons from both iodide and bromide ions. Those electrons will not be reclaimed by bromine and iodine from the produced chloride ions.
Is HCl a reducing agent?
HCl is an oxidizing compound, because 2H+ + 2e- –> H2 ( St. E.P. = 0.00 V) and Chloride ions are a very weak reducing agent (2Cl- –> Cl2 + 2e- at St.
Is Zn a reducing agent?
The zinc causes the sulfur to gain electrons and become reduced and so the zinc is called the reducing agent . The oxidizing agent is a substance that causes oxidation by accepting electrons. The reducing agent is a substance that causes reduction by losing electrons.
Is ki a strong reducing agent?
Under acidic conditions, KI is oxidised even more easily, due to the formation of hydroiodic acid (HI), which is a powerful reducing agent . ... Potassium iodide also serves in some organic reactions as a source of iodide ion (see “uses” below).
Is calcium a reducing agent?
Calcium is an excellent reducing agent and is widely used for this purpose. ... Calcium metal and most calcium compounds are nontoxic.
Is fluorine a strong reducing agent?
Fluorine acts as a stronger reducing agent than oxygen .
