Solvents01:12

Solvents

71.4K
A solvent is a substance, most often a liquid, that can dissolve other substances. Here, the substance being dissolved is called a solute. When a solvent and a solute combine, they form a solution - a homogenous mixture of both the solvent and the solute. Water is a universal biological solvent. Its polar structure allows it to dissolve many other polar compounds. The ability of water to dissolve is governed by a balance between water molecules binding to each other and binding to the solute.

Synthesis and Decomposition Reactions02:17

Synthesis and Decomposition Reactions

38.4K
Synthesis and decomposition are two types of redox reactions. Synthesis means to make something, whereas decomposition means to break something. The reactions are accompanied by chemical and energy changes.

Oxidation Numbers03:14

Oxidation Numbers

43.1K
In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the oxidation number (or oxidation state). It represents the effective charge of an atom or element, which is assigned using a set of rules.

Titration in Nonaqueous Solvents01:16

Titration in Nonaqueous Solvents

1.4K
Most acid-base titrations are performed in an aqueous medium. In aqueous titrations, water competes with weaker acids or bases for proton donation or acceptance, leading to ambiguous endpoints in the titration curve. Water also affects the partial ionization of weak acids or bases. For example, water accepts a proton from acetic acid to form hydronium and acetate ions. The hydronium ion formed is a stronger acid than acetic acid, and the acetate ion is a stronger base than water. As a result,...

Pyruvate Oxidation01:15

Pyruvate Oxidation

169.4K
After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure that pyruvate can enter the next metabolic pathway so that energy stored in the pyruvate molecules can be harnessed by the cells.
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Background:

  • Persistent organic pollutants (POPs) in wastewater pose significant environmental and health risks.
  • Advanced oxidation processes (AOPs) are effective for degrading POPs, but catalyst efficiency is crucial.
  • Greener synthesis methods for catalysts are needed to reduce environmental impact.

Purpose of the Study:

  • To review recent advances in using deep eutectic solvents (DES) for synthesizing catalysts in AOPs.
