WebDec 19, 2024 · 9. I think it's Hydrogen, because, P b O + H X 2 P b + H X 2 O. Here P b O is reduced to P b and H X 2 acts as a reducing agent. But, in 2 K + H X 2 2 K H, hydrogen gains a electron and undergoes reduction Thus, K is oxidized to K H and hydrogen works as oxidizing agent. My teacher says it's wrong but doesn't give any explanation. WebHence, H 2 O 2 can act as an oxidising as well as a reducing agent. In ozone (O 3), the O.N. of O is zero and the range of the O.N. that O can have is from 0 to –2. Therefore, the O.N. of O can only decrease in this case. Hence, O3 acts only as an oxidant. ... Statement 2: Hydrogen peroxide can never act as a reducing agent.

WebNov 2, 2024 · (A) Ozone as an oxidising agent : Since ozone decomposes to liberate nascent oxygen, it is a powerful oxidising agent next to fluorine. O 3(g) → O 2(g) + O. For example : It oxidises lead sulphide (PbS) to lead sulphate (PbSO 4) changing the oxidation state of S from – 2 to +6.. PbS (s) + 4O 3(g) → PbSO (s) + 4O 2(g). Potassium iodide, KI … WebJul 20, 2024 · In the world of redox chemistry there exist substances that can act as both a reducing agent and oxidizing and a couple of examples are given below. Water. We have seen that some oxidizing agents, such as fluorine, can oxidize water to oxygen. There are also some reducing agents, such as lithium, which can reduce water to hydrogen. WebThe most frequently used reducing agents are sulphur dioxide (gas supplied in its liquefied form) and sodium bisulphite (available as a 23-24% SO 2 aqueous solution) that act according to the following reactions: The reactions take place quickly in such a way that, in drinking water distribution systems, the contact time available in the ... cryptids minnesota
