Which of the following accurately describes oxidation?
Which of the following accurately describes oxidation?
The process by which a molecule loses electrons and decreases in energy is called oxidation.
Which of the following describes oxidation?
Oxidation is loss of electrons (OIL RIG). Therefore, an oxidizing agent takes electrons from that other substance. Therefore, an oxidizing agent must gain electrons.
What is the term oxidation?
Oxidation is defined as a process in which an electron is removed from a molecule during a chemical reaction. What happens in oxidation? During oxidation, there is a transfer of electrons. In other words, during oxidation, there is a loss of electrons.
Which of the following is the definition of oxidation Mcq?
Oxidation-Reduction reactions are reactions that involve the transfer of electrons between chemical species. A simple definition of redox reactions considers oxidation as the gain of oxygen atoms and reduction as the loss of oxygen atoms.
Is example of redox indicator?
The most common redox indicator are organic compounds. Redox Indicator example: The molecule 2,2′- Bipyridine is a redox Indicator….pH dependent.
| Indicator | Sodium 2,6-Dibromophenol-indophenol or Sodium 2,6-Dichlorophenol-indophenol |
|---|---|
| E0, V at pH=0 | +0.64 |
| E, V at pH=7 | +0.22 |
| Color of Oxidized form | blue |
What are oxidation reactions?
According to basic chemistry, oxidation reactions are those when a substrate is oxidized by an oxidant so that atoms of the substrate increase their oxidation numbers while atoms of the oxidant are reduced.
What is oxidation give example?
The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium. In the course of this reaction, each magnesium atom loses two electrons to form an Mg2+ ion.
What is oxidation in terms of electrons?
Oxidation is the loss of electrons, gain of oxygen or loss of hydrogen. Reduction is the gain of electrons, loss of oxygen or gain or hydrogen.
What is another word for oxidation?
What is another word for oxidation?
| tarnish | discoloration |
|---|---|
| blackening | film |
| patina | rust |
| tarnishing |
What is known as Autoxidation?
Autoxidation (sometimes auto-oxidation) refers to oxidations brought about by reactions with oxygen at normal temperatures, without the intervention of flame or electric spark. The term is usually used to describe the degradation of organic compounds in air at ambient temperatures.
What is known as Autoxidation Class 11?
Explanation: Autoxidation is any oxidation that occurs in presence of oxygen. The term is usually used to describe the degradation of organic compounds in air (as a source of oxygen). Autoxidation produces hydroperoxides and cyclic organic peroxides. These species can react further to form many products.
What is redox titration give example?
Ans: The redox titration is a type of titration which is based on a redox reaction between the analyte and the titrant. It also involves the use of a potentiometer or a redox indicator. An example of this type of titration is treating an iodine solution with a reducing agent.
