Difference between dissolution and chemical reaction. No comments:. Newer Post Older Post Home. This is the typical action of a solvent. Solvents are either polar or non-polar. A polar solvent has partial negative and positive charges. For instance, water has a partial negative charge on O and a partial positive charge on H. This helps the solvent interact with solvate ions and polar molecules through Coulomb interactions.
A non-polar solvent is one that is electrically neutral all over, or almost so. He says a substance may dissolve completely but it may not dissociate completely and a substance may not dissolve completely but amount that dissolves can dissociate completely and, thus, substances which dissolve either wholly or partially , amount that gets dissolved if dissociate completely are called strong electrolytes and amount of substances which gets dissolved if dissociates sparingly are called weak electrolytes although it may dissolve completely.
If solubility and dissociation are different then what would be the criteria for getting dissolved and what will be criteria for getting dissociated for me the criteria for getting dissolved is dissociation. Because NaCl is an ionic solid, the only way it can dissolve 3 is to also dissociate. Glucose is a molecular solid, so it only dissolves 1. Glacial acetic acid is a molecular liquid, and it dissolves in water and then partially dissociates 3 , whereas sulfur trioxide dissolves in water and then reacts with it 4.
Some transition metals cations hang on to their counter anions, or pick up some more in solution, together with water as a ligand. The highest chloro complex, [ZnCl4]2-, is tetrahedral with a Zn-Cl bond length of 2. The average Zn-Cl distance in these complexes is 2. So for these metal cations, the story is complicated and there is a complex mixtures of species, with concentrations dependent on anion concentrations, pH and temperature.
A classic example is cobalt chloride, where you can follow the equilibrium easily because of color changes, see e. This is a simple logical and semantic problem, which is not a problem at all. Your professor is right and wrong- both at the same time.
He is creating a classification which does not exist and which is meaningless. Compare electrolysis n. Compare French -lyte, German -lyt.
A substance which gives rise to ions when dissolved typically in water or fused; a liquid or gel which contains ions and can be decomposed by electrolysis; spec. By definition, an electrolyte is soluble in a given solvent. It is also understood among electrochemists that an electrolyte is added to a solvent to impart conductivity to that solvent. I will never call sugar an electrolyte because nobody would use sugar to increase conductivity of water. You should ask: Does a given substance produce ions in a solution?
If yes, it can be called as an electrolyte. Electrolytes are soluble in the solvent, but not all soluble substances in that solvent behave as electrolytes. Anything which produces ions in that solvent, can be labelled as an electrolyte. Q-1 If solubility and dissociation are different then what would be the criteria for getting dissolved and what will be criteria for getting dissociated for me the criteria for getting dissolved is dissociation.
The measure of dissociation is conductivity. How much electrical resistance is offered by that dissolved and dissociated substance in that solvent.
There is no correlation between solubility and dissociation. If I want to study their dissociation I will measure the conductivity of their solutions systematically.
Dissociation, in chemistry, the breaking up of a compound into simpler constituents that are usually capable of recombining under other conditions. In electrolytic, or ionic, dissociation, the addition of a solvent or of energy in the form of heat causes molecules or crystals of the substance to break up into ions electrically charged particles.
Most dissociating substances produce ions by chemical combination with the solvent. The idea of ionic dissociation is used to explain electrical conductivity and many other properties of electrolytic solutions.
However, per Wikipedia , to quote:. It does not hydrolyze when it enters water, and is usually handled as a dissolved gas in solution in water.
