bond: A strong electrostatic interaction between two ions of opposite charge. Ionic bonds are formed between elements with a large difference in electronegativity, so ionic compounds are often composed of a metal (especially an alkali metal or alkaline earth metal) cation and a nonmetal anion. ...
When an element is referred to as an ion and not a cation or anion, is the charge negative or positive by default?Naming an AnionThe ions formed from nonmetallic elements are often named by affixing the suffix "-ide" to the name of the e...
Chlorine (Cl) is a larger anion.- According to Fajans' rules, a small cation with a high charge can polarize the electron cloud of a larger anion, leading to covalent character in the bond.- Therefore, LiCl exhibits more covalent character due to the small size and high polarizing power ...
the sodium and chlorine atoms form into a crystal structure in which each sodium atom is surrounded by chlorine atoms and vice versa. When salt dissolves in water, the structure separates into Na+and Cl-ions.
The beads are converted into cation-exchange resins through sulfonation or anion-exchange resins through chloromethylation. Ion-exchange resins pick-up positively or negatively charged particles from the water stream. The main targets for removal are boron, trihalomethane and perchlorates. An acid or...
CONSTITUTION: The catalyst system comprises the phenolate/chlorine complex compound of the following formula: Me<+n> [Z<+m> Clm.L]n. In the formula, (n) is an integer of 1 to 3; (m) is an integer of 1 to 6; Cl is chloride anion; Me is H and/or a metallic cation of the ...
at depth. The shallow aquifer occurs within an average depth of 16 m. The configuration of water table in the shallow aquifer follows the topography due to which the groundwater movement is generally toward valleys or topographic lows. The water bodies, such as tanks, canals, and streams. als...
Isothiazolinones (CMIT/MIT)can mix with chlorine and most cation, anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent. Isothiazolinones (CMIT/MIT)is a kind of fungicidal with properties of broad spectrum, high efficiency, low toxicity and non-...
Salts that are from strong bases and strong acids do not hydrolyze. ThepH will remain neutral at 7. Halides and alkaline metals dissociate and do not affect the H+as the cation does not alter the H+and the anion does not attract the H+from water. This is why NaCl is a neutral salt...
One way to remember the definitions of cations and anions is to think of the letter "t" in the word cation as looking like a plus symbol. The letter "n" in anion is the starting letter in the word "negative" or is a letter in the word "anion." ...
