What is the term for a reaction in which a substance gains electrons?

What is the term for a reaction in which a substance gains electrons?

Explanation: Reduction is the process in which substance gain electrons. The reactant is become reduced and has a negative charge, once it gains electrons. In the reduction process, oxidation number get decrease by gaining the electrons.

What is redox reaction in cellular respiration?

Cellular respiration involves many reactions in which electrons are passed from one molecule to another. Reactions involving electron transfers are known as oxidation-reduction reactions (or redox reactions).

Why is respiration a redox reaction?

Respiration is a set of metabolic reactions, where there is both loss and gain of electrons. Therefore, it is called the oxidation-reduction or redox reaction.

What are oxidizing and reducing agents give examples?

Some compounds can act as either oxidizing agents or reducing agents. One example is hydrogen gas, which acts as an oxidizing agent when it combines with metals and as a reducing agent when it reacts with nonmetals. Another example is hydrogen peroxide, in which the oxygen atom is in the -1 oxidation state.

Is calcium a stronger reducing agent than magnesium?

For example, among Na, Cr, Cu+ and Cl−, Na is the strongest reducing agent and Cl− is the weakest one. Common reducing agents include metals potassium, calcium, barium, sodium and magnesium, and also compounds that contain the H− ion, those being NaH, LiH, LiAlH4 and CaH2.

Which among the following is strongest reducing agent?

The species with the lowest electrode potential is the strongest reducing agent i.e. Fe2+.

Is potassium permanganate a reducing agent?

Potassium permanganate is widely used in chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection.

Which among the following is the strongest reducing agent 1 k2 Na 3 Al 4 mg?

Na = -2.71 V, Mg = -2.38 V, Al = -1.66 V, and K = -2.92 V. Larger is the value of electrode potential stronger will be reducing power of an element. Hence, we can conclude that out of the given options K is the strongest reducing agent./span>

Which of the following is the strongest reducing agent in aqueous solution?

In an aqueous medium, Li is the strongest reducing agent, since the high negative enthalpy of hydration compensates high IE1./span>

Which Halogen is strongest reducing agent?

Fluorine

Which is the best oxidizing agent?

The strongest oxidant in the table is F2, with a standard electrode potential of 2.87 V. This high value is consistent with the high electronegativity of fluorine and tells us that fluorine has a stronger tendency to accept electrons (it is a stronger oxidant) than any other element./span>

Which is a stronger reducing agent Cr2+ or Fe2+ and why?

Answer: Cr2+ is a stronger reducing agent than Fe2+. This can be explained on the basis of the standard electrode potential values E°(Cr3+/Cr2+ = –0.41 V) and E° (Fe3+/Fe2+ = + 0.77 V). Thus Cr2+ is easily oxidised to Cr3+ but Fe2+ cannot be as readily oxidised to Fe3+.
