due to th H3PO$ has 3 ionization steps any step give hydrogen ion (H2PO4 + H and HPO4 + H)with one electron which compine with other hydrogen to give hydrogen gas and two electron which make redction reaction and soon

∙ 9y agoHydrogen phosphite can not (easily) be reduced to phosphorus (P) by taking up 3 electrons when reacting as oxidant. The only oxidant action could come from H+ (forming H2 gas, eg. with reactive metals)
Acting as reductant phosphate (H3PO4 ) is formed (by 2 electrons donation) quite easily

Is helium a good reducing agent?
no. helium is chemically inert.
Why NH3 is poor reducing agent while BiH3 is a strong redusing agent?
A good reducing agent is something that can easily lend a hydrogen atom. Nitrogens Hydrogens are in a subshell that is much closer to the nucleus of the Nitrogen atom. This smaller radius results in a greater attraction between the electrons H+ and N share. Bismuth (Bi) has a much larger radius, so the forces are more diluted, and the H+ is more easily removed from the Bi. Because the Nitrogens H+ in NH3 is harder to remove it is a mild reducing agent. Bismuth has a H+ that can be removed easily so it is a stronger reducing agent.
Why the conc h2so4 cant be used in preparation oh h2s?
h2so4 being good oxidising agent oxidises the h2s to h2o and free sulphur.so conc h2so4 cant be used in preparation of h2s gas
What atom is known as an electron grabber because it attract electron so strongly?
Fluorine is the best. Any element with a high electronegativity. Oxygen next then chlorine. Anything that is considered a good oxidising agent will grab electrons.
Is magnesium a good or bad reducing agent?
Quite good, just a bit better than Zinc, hardly better than Aluminum, and less than Sodium (Na), Ca, Ba, K and Li
Is gold a reducing agent or a oxidising agent?
Strong Oxid. Agent bcs Reduction Potential is too high.
Why does SO2 act as a good reducing agent as well as oxidising agent?
not sure about it yet but you may try wish123. Might help you. thanks
What is a good reducing agent?
A substance that is good at reducing another atom
Which is good oxidising agent PbO2 or PbO?
PbO2....Pb has a 4+ charge and therefore can be reduced to Pb2+ in PbO. Since it can be reduced it is an oxidizing agent.
What is a reducing agent in chemistry?
A substance that is good at reducing another atom
Is helium a good reducing agent?
no. helium is chemically inert.
Why is sulfuric acid added to sodium ethanedioate and hydrated ethanedioic acid?
to acidify the solution so that it can become a good oxidising agent
Is citric acid a good reducing agent?
I would say yes.
Is h2o2 a part of oxygen?
H2O2 is commonly known as hydrogen peroxide and is a very good oxidising agent, which is commonly found in hair dyes. It can also be known as dihydrogen dioxide and dioxidane.
Why is carbon dioxide not good reducing agent as carbon monoxide?
The carbon atom in carbon dioxide has an oxidation state of 4+ (It's missing 4 electrons.) The carbon atom in carbon monoxide has an oxidation state of 2+ (It's only missing two electrons.) A reducing agent is something that will give electrons to another substance. Carbon dioxide has less electrons to give than carbon monoxide, making it not as good of a reducing agent.
Why alkali metals are good reducing agent?
Alkali metal have a strong tendency to lose electrons and act as good reducing agents. The reducing character increases from sodium to caesium. However lithium is the strongest reducing agent.ReasonThe alkali metals have low value of ionization energy which decreases down the group and so can easily lose their valence electron and thus act as good reducing agents.
