anion vs cation

anion cation

Definitions

  • 1) An negatively charged ion.
  • 2) A negatively charged ion, especially the ion that migrates to an anode in electrolysis.
  • 3) (Chem.) An electro-negative atom or group of atoms, or the element which, in electro-chemical decompositions, is evolved at the anode; -- opposed to cation.
  • 4) (Chem.) An electro-negative atom or group of atoms, or the element which, in electro-chemical decompositions, is evolved at the anode; -- opposed to cation.
  • 5) a negatively charged ion
  • 6) In electricity, a term applied by Faraday to that element of an electrolyte which in electrochemical decompositions appears at the positive pole, or anode, as oxygen or chlorine.

Definitions

  • 1) chemistry A positively charged ion—opposed to anion.
  • 2) chemistry The ion in an electrolyzed solution that migrates to the cathode.
  • 3) chemistry A positively charged ion—opposed to anion.
  • 4) chemistry The ion in an electrolyzed solution that migrates to the cathode.
  • 5) An ion or group of ions having a positive charge and characteristically moving toward the negative electrode in electrolysis.
  • 6) (Chem.) a positively charged atom, radical, or molecule, which in electrolysis migrates to the cathode; a positive ion; -- opposed to anion.
  • 7) (Chem.) a positively charged atom, radical, or molecule, which in electrolysis migrates to the cathode; a positive ion; -- opposed to anion.
  • 8) a positively charged ion

Examples

  • 1) The molecule is a chain of eight carbons and a single hydrogen called the octatetraynyl anion C8H¯.
  • 2) The chemical conditions that define acidity are that acid anion concentrations (sulfate, nitrate, organic acids) are present in excess of concentrations of base cations (typically calcium or magnesium), the products of mineral weathering reactions that neutralize acidity in soil or rock.
  • 3) But surely you understand that there is polarity in nature (cation/anion, stamen/pistil, male/female), a condition in which complimentary opposites exist in a synergistic fashion to produce and create.
  • 4) Production of NADPH dropped by 30 percent and superoxide anion dropped by a whopping 74 percent.
  • 5) Defective anion transport activity of the abnormal band 3 in hereditary ovalocytic red blood cells.
  • 6) An atom that becomes negatively charged due to an excess of electrons is called an anion, a negatively charged ion.
  • 7) Groundwater interactions with surface-water systems greatly influence water quality characteristics such as cation, anion, nutrient, and dissolved organic matter concentrations, and even the fate and behavior of toxic pollutants.
  • 8) My question is this: since BAS drugs operate via a non-absorbed, non-systemic action they are anion-exchange resins, are they at all dangerous?
  • 9) The ocean carbon cycle comprises a physical pump, a biological pump, and an alkalinity or anion pump.
  • 10) ‘When two atoms swap electrons to produce a cation and an anion, the two ions are attracted to each other.’
  • 11) ‘During electrolysis an anion is attracted to the anode (positive electrode).’
  • 12) ‘In an ionic compound there are two different types of ions present, the positively charged cations and the negatively charged anions.’
  • 13) ‘It is called a cation if a positive charge exists and an anion if a negative charge exists.’
  • 14) ‘It's easy to make a high oxidation state in an anion because an anion is electron-rich.’
  • 15) ‘All the positively charged ions, or cations, are together on the right side of the collage, and all the negatively charged ions, or anions, are on the left.’
  • 16) ‘An ionic compound is composed of a network of ions that results in a three-dimensional matrix of cations and anions.’
  • 17) ‘For ions dissolved in water, the rapid exchange of water molecules around the cation usually provides the space for an anion to approach the cation.’
  • 18) ‘The cation is positively charged, and the anion is negatively charged.’
  • 19) ‘Non-metals accept electrons in forming anions while metals donate electrons to form cations.’
  • 20) ‘These water molecules are ripped apart and change into hydroxyl anions, each of which is negatively charged and has one oxygen ion with a proton attached.’
  • 21) ‘The molecules or anions attached to the central atom are called coordinating groups or ligands.’
  • 22) ‘Cations within the middle solution are attracted to one electrode and anions to the other.’
  • 23) ‘A typical reaction of such compounds is to accept an additional electron from an anion or to share electrons with an anion to gain a stable octet.’
  • 24) ‘Nitric oxide can react with superoxide anions to produce peroxynitrite anions, thus quenching the biological effects of NO.’
  • 25) ‘To balance the influx of positive charge, organic anions, principally malate, and chloride are also accumulated.’
  • 26) ‘Crystals of table salt consist of equal numbers of sodium cations and chlorine anions, cation-anion pairs being held together by a force of attraction.’
  • 27) ‘Cations and anions can only exist in ionic compounds, nearly all of which are solids at room temperature, or in solution.’
  • 28) ‘The functional groups of iron hydroxides may sequestrate some cations and anions.’
  • 29) ‘Protons diffuse across a membrane from the anode chamber to the cathode chamber, where they react with the anions to form water or ferrocyanide ions.’

Examples

  • 1) The recession has been among us for long enough now that the "stay-cation" is no longer a novel concept.
  • 2) As a result, the iron cation is released, but the apo-transferrin, which has high affinity for the receptor at acidic pH, remains bound strongly.
  • 3) In the words of soil science, this functioning like a storage battery for minerals is called cation exchange capacity.
  • 4) Any element with a positive charge is called a cation and, for agricultural purposes, it refers to the basic cations, calcium (Ca+2), magnesium (Mg+2), potassium (K+1) and sodium (Na+1) and the acidic cations, hydrogen (H+1) and aluminum (Al+3).
  • 5) Groundwater interactions with surface-water systems greatly influence water quality characteristics such as cation, anion, nutrient, and dissolved organic matter concentrations, and even the fate and behavior of toxic pollutants.
  • 6) If you cant figure out the area of a triangle or what "cation" means, you die! if you cant take down a demon w/a chainsaw or kill a hell prince w/a shotgun, you die! f--- ing snotty rich f--- heads.
  • 7) LOOK at the image title at the top that frontpage sends you to - it says "cation" which means it is an ABSTRACT with some info from the certifiCATE.
  • 8) And so it was with me during my "work-cation," when I spent the dog days thinking about how to make better virtual meetings -- the kind of meetings many employees experience when they're working remotely or enjoying a holiday.
  • 9) A new word, 'stay-cation' entered the tourism industry vocabulary last year.
  • 10) ‘When two atoms swap electrons to produce a cation and an anion, the two ions are attracted to each other.’
  • 11) ‘The key step in a unimolecular reaction is the formation of the carbon cation, or carbonium ion, by the departure of the leaving group.’
  • 12) ‘The functional groups of iron hydroxides may sequestrate some cations and anions.’
  • 13) ‘It is called a cation if a positive charge exists and an anion if a negative charge exists.’
  • 14) ‘Non-metals accept electrons in forming anions while metals donate electrons to form cations.’
