Electrolyte. An electrolyte is a medium containing ions that are electrically conductive through the movement of those ions, but not conducting electrons. [1] [2] [3] [clarification needed (see talk)] This includes most soluble salts, acids, and bases, dissolved in a polar solvent like water. Upon dissolving, the substance separates into ...
A hydrogen atom is made up of a nucleus with charge +1, and a single electron. Therefore, the only positively charged ion possible has charge +1. It is noted H + . Depending on the isotope in question, the hydrogen cation has different names: Hydron: general name referring to the positive ion of any hydrogen isotope (H +)
The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential (region ...
Lugol's iodine, also known as aqueous iodine and strong iodine solution, is a solution of potassium iodide with iodine in water. [2] It is a medication and disinfectant used for a number of purposes. [3] [4] Taken by mouth it is used to treat thyrotoxicosis until surgery can be carried out, protect the thyroid gland from radioactive iodine, and ...
Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper (II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars. The presence of other reducing substances ...
A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...
Dissociation of Gomberg's dimer. Dissociation diagram of phosphoric acid. Dissociationin chemistryis a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.
A micelle ( / maɪˈsɛl /) or micella ( / maɪˈsɛlə /) ( pl. micelles or micellae, respectively) is an aggregate (or supramolecular assembly) of surfactant amphipathic lipid molecules dispersed in a liquid, forming a colloidal suspension (also known as associated colloidal system). [4] A typical micelle in water forms an aggregate with the ...
