What is the function of coke in a blast furnace?
Coke is used in a blast furnace as a fuel and reducing agent. It provides the heat needed to melt iron ore and other materials to produce molten iron. Additionally, coke reacts with oxygen in the air to remove impurities from the iron ore, helping to create higher-quality molten iron.
How can vitamin C function as an antioxidant?
Vitamin C acts as an antioxidant by reducing the concentration of oxygen. This is possible as it is a reducing agent.
What is reducing agent in Ca Br2--CaBr2?
In the reaction Ca + Br2 → CaBr2, calcium acts as the reducing agent because it undergoes oxidation by losing electrons to bromine. This results in the formation of calcium bromide (CaBr2).
Is oxygen the oxidizing agent in combustion and the reducing agent in corrosion?
Yes, in combustion, oxygen acts as the oxidizing agent because it gains electrons from the fuel being burned. In corrosion, however, oxygen acts as the oxidizing agent as it accepts electrons from the metal, causing it to corrode or rust.
What is coke in chemistry?
In chemistry, "coke" refers to a porous, carbon-rich material that is produced when coal is heated in the absence of air. It is primarily composed of carbon with small amounts of ash and sulfur. Coke is commonly used as a fuel and as a reducing agent in various industrial processes, such as in the production of steel.
What is the function of coke in a blast furnace?
Coke is used in a blast furnace as a fuel and reducing agent. It provides the heat needed to melt iron ore and other materials to produce molten iron. Additionally, coke reacts with oxygen in the air to remove impurities from the iron ore, helping to create higher-quality molten iron.
Why does coke act as reducing agent?
Coke is a reducing agent because it is a source of carbon which can donate electrons to other substances during a chemical reaction. The carbon in coke can react with oxygen or other compounds, reducing them by giving up electrons. This ability to donate electrons allows coke to act as a reducing agent in various chemical processes.
Is citric acid a good reducing agent?
No, citric acid is not a reducing agent. It acts as a weak acid and does not typically participate in reduction-oxidation (redox) reactions as a reducing agent.
Why is coke added to the iron ore in a bast furnace?
Coke is added to the iron ore in a blast furnace because it is used as a fuel to provide the high temperatures needed for the chemical reactions to occur. When coke is burned, it produces carbon monoxide, which acts as a reducing agent and helps to remove oxygen from the iron ore to produce molten iron.
How can vitamin C function as an antioxidant?
Vitamin C acts as an antioxidant by reducing the concentration of oxygen. This is possible as it is a reducing agent.
Why SO2 acts as a reducing agent?
Sulfur dioxide (SO2) acts as a reducing agent because it can easily be oxidized to sulfuric acid (H2SO4) by gaining oxygen atoms. In this process, another substance is reduced by gaining electrons from SO2, making it a reducing agent.
Is iron an oxidizing agent or reducing agent?
Zinc is a transition element with general oxidation state as +2. It gets easily oxidised to its oxidation state of +2 by elements which are less reactive than zinc . For example: 2Zn + H2O --> Zn2O + H2
What are the raw materials fed into the blast furnace?
The raw materials fed into the blast furnace typically include iron ore, coke (a form of carbon), and limestone. Iron ore is the primary source of iron, coke acts as a fuel and reducing agent, while limestone helps remove impurities during the smelting process.
Is iodine a oxodizing agent?
No, iodine is not an oxidizing agent. It typically acts as a reducing agent, meaning it tends to gain electrons rather than lose them in chemical reactions.
How do you redox titration by Potassium Permanganate?
In a redox titration using potassium permanganate, the permanganate ion (MnO4-) acts as the oxidizing agent while the other substance being titrated acts as the reducing agent. The endpoint is reached when all the reducing agent has been consumed, leading to a color change from purple to colorless or light pink. The volume of potassium permanganate solution required to reach the endpoint is used to calculate the concentration of the reducing agent.
What role does the reducing agent play in a blast furnace?
The reducing agent grabs oxygen or other impurities from the molten metal so making a more refined productFor example, coke reduces ZnO to Zn and Fe2O3 to Fe
What is reducing agent in Ca Br2--CaBr2?
In the reaction Ca + Br2 → CaBr2, calcium acts as the reducing agent because it undergoes oxidation by losing electrons to bromine. This results in the formation of calcium bromide (CaBr2).
