Which one of the following is the strongest reducing agent?

Lithium

Which of the following is only reducing agent?

KMnO4​

Is hno3 a reducing agent?

In nitric acid, the oxidation state of nitrogen is +5, that is the maximum oxidation state nitrogen can acquire in a compound. So it can get oxidised to +5 state and also get reduced to -3 state. Thus, it can act as both reducing agent and oxidising agent.

Which of the following is reducing agent po43?

H3PO3 acts as a reducing agent, whereas H3PO4 does not. This can be explained on the basis of their structure. Due to presence of unstable P-H bond H3PO3, it acts as a reducing agent.

Can SO3 act as reducing agent?

SO3 is not used as a reducing agent since it cannot donate a lone pair of electrons. The bleaching action of sulphur is based on oxidation.

Can clo2 act as reducing agent?

CO2 cannot act as reducing agent because C in CO2 has an oxidation state of +4 . C can have a maximum of +4 oxidation state, it cannot increase the oxidation state beyond +4 thus CO2 cannot undergo oxidation thus it cannot act as a reducing agent.

Is nitrogen dioxide a reducing agent?

nitrogen oxides It is a strong oxidizing agent that decomposes upon heating to form nitrogen and oxygen. Because one-third of the gas liberated is oxygen, nitrous oxide supports combustion better than air. All the nitrogen oxides are, in fact, good oxidizing agents.

Is chlorine a reducing agent?

Chlorine has the ability to take electrons from both bromide ions and iodide ions. Bromine and iodine cannot reclaim those electrons from the chloride ions formed. This indicates that chlorine is a more powerful oxidizing agent than either bromine or iodine.

Which gas is strong oxidizing agent?

An example is the release of oxygen from hydrogen peroxide, release of nitrous or nitric oxide by nitric acid, and the generation of chlorine gas from hypochlorites….Oxidizing Agents.

What is the strongest oxidant?

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.

Is water an oxidant?

In the presence of a strong electron donor (strong reducing agent), water serves as an oxidizing agent. In the presence of a strong electron acceptor (strong oxidizing agent), water serves as a reducing agent.

What is the weakest reducing agent?

The following table provides the reduction potentials of the indicated reducing agent at 25 °C. For example, among Na, Cr, Cu+ and Cl’, Na is the strongest reducing agent and Cl’ is the weakest one.

Which hydride is strongest reducing agent?

BiH2

Which is the best reducing agent in gas phase?

Since, ionization decreases on moving down from Li to Cs, the reducing property increases in same order. Thus, Li is the weakest reducing agent while Cs is the strongest reducing agent amongst alkali metals in a free gaseous state.

Which is the weakest reducing agent Li Na K Rb?

As such Na is the weakest reducing agent among the alkali metals.

Which element has lowest reduction?

Lithium has the strongest ability to lose electron. Fluorine is at the bottom of the table has highest reduction potential. It is the weakest reducing agent or the strongest oxidizing agent with lowest ability to lose electron or highest ability to gain electron and get reduced.

Which alkali metal is the weakest reducing agent?

Li

Which alkali metal is strong reducing agent?

Which alkali metal has lowest power?

sodium

Why are alkali metals difficult to be reduced?

Ans: Alkali metals are highly electropositive in nature, these metals readily donate electrons to get stability. These metals does not accept electrons (as taking of electrons does not give stability), therefore it is difficult to reduce alkali metals.

Why alkali metals are strong reducing agent?

They can attain the noble gas electronic configuration by the removal of one electron which is a stable configuration. Due to low ionization potential and having the smallest nuclear charge they can easily lose an electron. Hence, alkali metals are considered as a powerful reducing agent.
