Description NuPAGE Sample Reducing Agent (10X) is used to reduce protein samples for protein gel electrophoresis. Published on 19 Jan 2016. Aluminium has a great affinity towards oxygen and so cannot be reduced by carbon or carbon monoxide. A reducing agent is a substance that causes another substance to reduce. As we move upwards from hydrogen in the electrochemical series then the strength of reducing agents decreases. So it is extracted from its oxide by electrolysis. The substance which give hydrogen or removes oxygen. Corrosion . Our mission is to provide a free, world-class education to anyone, anywhere. Question 2. Oxidation state of iron as a reactant is 0 while +2 as a product in the reaction. Example: Mg^+2 + S^-2 = MgS Magnesium donates its two electrons to sulfur, so magnesium is the reducing agent and sulfur is the oxidizing agent. Practice to excel and get familiar with the paper pattern and the type of questions. Redox reactions grade 11 2. Or. Or. Those reactions in which oxidation and reduction occurs simultaneously are called Redox Reaction. State why aluminium is extracted from its oxide by electrolysis while copper, lead, iron by reducing agents and mercury and silver by thermal decomposition. are weak reducing agents. Pre Boards. Last Updated on May 3, 2019 By Mrs Shilpi Nagpal 3 Comments. Strong reducing agent like electricity is used in the production of these metals by the electrolysis of their molten metallic compounds. In this reaction, oxygen is removed from copper and oxygen is added to hydrogen. So its oxide is less stable and hence it can be reduced by reducing agent whereas aluminium is very reactive due to which its oxide is quite stable and it can not be reduced by reducing agent it can be reduced only by electrolytic reduction. ... ICSE Class 10 Chemistry Solved Question Paper 2015. Question 10. Copper is produced by the oxidation-reduction reactions of metal sulfide. Thus, we can say when an element gets oxidized, its oxidation state increases while in reduction it decreases. The time given […] Oxidizing Agent: An oxidizing agent is a substance that can be reduced by obtaining electrons. A reducing agent reduces something else. Answer: As you can see, the oxidation state of zinc is increasing so it's getting oxidized.

It is best Before understanding what are reducing agents, you need to know what reduction and oxidation is? Repeaters, Vedantu F2 (Fluorine) is a Reducing Agent. | EduRev Class 10 Question is disucussed on EduRev Study Group by 107 Class 10 Students. Practice to excel and get familiar with the paper pattern and the type of questions. This diagram shows that the oxidizing agent gains electrons from another substance, which is the reducing agent. When cupric oxide reacts with hydrogen, it gives copper and water. Many other oxidizing agents are commonly used industrially as well as in the day-to-day lives of humans. This time is to be spent in reading the Question Paper. Answer: (a) catalyst. The reaction is given below showing oxidation and reduction – Image will be uploaded soon. Oxidising agents give oxygen to another substance or remove hydrogen from it. Redox reaction is defined as the class of reactions where oxidation and reduction coincide. (image will be uploaded soon). Answer: Metals are good reducing agents because they are electron donors. Explain with reason as to why the blue colour of aqueous copper sulphate solution fades away slowly when an iron rod is dipped into it. Question 10. What do you understand by precipitation reaction? And chlorine, by undergoing reduction, is taking the electrons from the 2 sodium atoms.
