Because of the polarity of water which causes one or two or more substances to break apart due to the unbalance of electrons in H20, which is actually neutral.
dissociation
Dissociation of what? Table salt, for example (NaCl) dissociates into Na+ and Cl- ions in water.
H2o --> h+ + oh-
Dissociation
The meaning of the term dissociation in chemistry is splitting of a compound (in water solution) in ions, radicals etc. Thermal dissociation is the reversible process performed by heating and when the molecule is splitted generally in a single step.
The dissociation constant of pure water is 1.9E-5.
dissociation, dispersion, and ionization
Dissociation of sodium chloride in water solution: NaCl -----------Na+ + Cl-
hydrogen and water
dissociation
This is a "reaction" with water, a dissociation of the salt in ions.
Another way to describe the dissociation of water is as follows where two water molecules form a hydronium ion (essentially a water molecule with a proton attached) and a hydroxide ion
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
Ions: H+ and OH-.
dissociation
Ions are obtained by dissociation in water.
Dissociation in chemistry is the process of splitting of an ionic compound in water solution. Association is the inverse process.
