Which of the following statement is correct? Statement 1: The addition of hydrogen to a substance and the removal of the oxygen from a substance is called oxidation. Statement 2: The addition of oxygen in a substance and the removal of  Hydrogen from a substance is called reduction.   Correct Answer Both are incorrect

The correct answer is 4 i.e. Both are incorrect.

Oxidation and Reduction:

  • The addition of oxygen to a substance and the removal of the hydrogen from a substance is called oxidation.
  • The addition of Hydrogen in a substance and the removal of oxygen from a substance is called reduction.
  • Oxidizing agent:
    • ​The substance which gives oxygen for oxidation is called an oxidizing agent.
    • The substance which removes hydrogen is also called an oxidizing agent.
  • Reducing agent: 
    • ​The substance which gives hydrogen for reduction is called a reducing agent.
    • The substance which removes oxygen is also called a reducing agent.
  • The oxidation and reduction reactions are also called redox reactions.
  • There is another concept of oxidation and reduction in terms of metals and non-metals. 
  • This is as follows: 
    • ​The addition of a non-metallic element (removal of metallic element) is called oxidation.
    • The addition of metallic elements (removal of non-metallic elements) is called reduction.

Mr.Rohan while helping the students of Class IV in adding and subtracting fractions observed that several students are not able to complete the addition of two improper fractions. He gave a small test with questions from the addition of proper fractions (one item of addition of two similar fractions, three items from the addition of proper and improper fractions, and four items from the addition of improper fractions). He analyzed the responses of each student and found that nearly 45% of students were not clear in adding proper with improper fractions which were affecting their performance in adding two improper fractions. He, therefore, focused on developing the understanding of improper fractions and their addition with proper fractions after which he proceeded to teach the addition of two improper fractions. Which kind of assessment is depicted by this situation?
What is the EMF of a galvanic cell if the standard oxidation potential of the oxidation half-reaction is 0.64 volts and the standard reduction potential of the reduction half-reaction is 0.48 volts?
With reference to the Green Hydrogen, consider the following statements: 1. Green hydrogen is produced with the help of electrolysis through electricity generated from renewable sources of energy such as solar and wind. 2. An electric current then splits the water into hydrogen and oxygen. 3. This ensures no greenhouse gas emissions as the only by-product of this process is oxygen, making it a great replacement for carbon-emitting fuels. Which of the above statement is/are correct?
What is the EMF of a galvanic cell if the standard reduction potential of the reduction half-reaction is -0.38 volts and the standard reduction potential of the oxidation half-reaction is 0.52 volts?
Air of 20.8% O2, concentration enters a coal mine panel at 20 m3/s and exits with 20.6% O2. The oxygen depletion is due to oxidation of carbon in spontaneous heating process only, assuming the density of oxygen as 1.3 kg/m3 and the calorific value of carbon as 34 MJ/kg, the heat generated in kW from the panel due to spontaneous oxidation is
In a well aerated and agitated microbial culture, the 'supply' of oxygen is equal to 'demand' (uptake) of the growing culture. The KLa for such a system will be (KLa = volumetric mass transfer coefficient, C* = dissolved oxygen concentration in liquid in equilibrium with gaseous oxygen, C = instantaneous value of dissolved oxygen concentration, 'r' = specific oxygen uptake rate per unit weight of cells, X = dry weight of the cells per unit volume)
Consider the following statements: 1. A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen. 2. The oxygen atom attracts the electrons more strongly than the hydrogen, this gives water an asymmetrical distribution of charge. 3. Molecules that have ended with partial negative and positive charges are known as polar molecules.  Which of the above statement is/are correct?
Which of the following statement about fuel cells are correct? Statement 1: Galvanic cells that are designed to convert the energy of the combustion of fuels like hydrogen, methane, methanol, etc. directly into electrical energy are called fuel cells.
