Dissociation is the process by which a molecule separates into ions. It may also be called ionization, but because there are other ways to form ions, the term dissociation is preferred. Substances dissociate to different degrees, ranging from substances that dissociate very slightly, such as water, to those that dissociate almost completely, such as strong acids and bases. The extent to which a substance dissociates is directly related to its ability to conduct an electric current. A substance that dissociates only slightly (as in the case of a weak acid like vinegar) is a weak electrolyte, as it conducts electricity poorly. A substance that is almost completely dissociated (such as table salt, NaCl, or hydrochloric acid, HCl) conducts electricity very well. The ability to conduct electricity is based on the ionic makeup of a substance. The more ions a substance contains, the better it will conduct electricity.

Why does NH3 give OH- ions on dissociation in water?

Ammonia is not a base when using the more widely known Arrhenius definition (which states that a base releases OH - and an acid releases H + . Instead, it is considered a base when using the Lewis definition , which states that a base is an electron pair donor , and an acid is an electron pair ac ( Full Answer )

What is a dissociation?

Dissociation is a chemical phenomenon: splitting of an ioniccompound in ions or radicals. This process is generally reversible.

What happens to water when it dissociates?

Water, which we know is H 2 O, will dissociate into a H + ion and an OH - ion. These are the hydronium and hydroxide ions, respectively. In its liquid form, water is doing this all the time, and it is also "reassociating" all the time as well.

Why does water cause dissociation?

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.

How does acetic acid dissociate in water?

Acetic acid will not dissociate in water very well. Here is the equation for the reaction: HC 2 H 3 O 2 (aq) + H 2 O (l) => H 3 O + (aq) + C 2 H 3 O 2 - (aq) In the reaction, a water molecule (H 2 O) "pulls" a hydrogen ion off the acetic acid and forms the hydronium (H 3 O + ) ion.

Which compound dissociates in water to form ions?

Any group one salts; Ca, Sr, Ba salts; nitrate salts; NH 4 salts; C 2 H 3 O 2 - salts; Cl, Br, I salts except AgCl, PbBr 2 , and Hg 2 Cl 2 ; SO 4 2- salts except BaSO 4 , PbSO 4 , Ag 2 SO 4 and SrSO 4 ; Group II carbonates are insoluble.

Describe the dissociation process when NaCl dissolves in water?

NaCl (sodium chloride), when placed into water, will dissociate respectively into sodium cations (Na+) and chloride cations (Cl-) when placed into water. Cl- becomes attracted to the hydrogen molecules in water whereas Na+ becomes attracted to the oxygen in the water thus forming salt water.

What is auto dissociation?

Autodissociation, or autoionization is the spontaneous separation of molecules into ions . A molecule, or a set of molecules will split up to form a number of positive charged particles ( cations ) and negative charged particles ( anions ). Autodissociation is usually associated with protic so ( Full Answer )

What is photochemical dissociation?

The meaning of the term dissociation in chemistry is splitting of acompound in ions, radials etc; photochemical dissociation is theprocess performed under irradiation with visible or ultravioletlight.

What is Functional dissociation?

it is hallucinating like when you are dreaming or when you take a psychoactive drug such as acid or mushrooms

Does Hcl dissociate in water?

The answer is "yes; HCl will dissociate in water". The simpleexplanation for this process is because HCl is aqueous. Thus, it'scations and its anions seperate when in water. This is the exactdefintion of "dissociation".

How does NH4Cl dissociate in water?

So NH4Cl(s) -----> NH4+(aq) + Cl-(aq). As NH4Cl is ionic you canassume it is a solid. Since H2O is polar it reacts with the NH4Clion in a way which allows it to dissociate the ion. The oxygen isslightly negative while the hydrogens have a partial positivecharge. The negativity of the oxygen in H2O c ( Full Answer )

What equation represents the dissociation of water molecules into hydrogen ions and hydroxide ions?

Before an equation is shown, it's important to point out that no hydrogen ions, H + , are actually formed when water self-ionizes, or dissociates as it is often called. The positively-charged species actually formed during water self-ionization is H 3 O + , the hydronium ion. However, using the hydr ( Full Answer )

When water dissociates each water molecule splits into?

Initially, each water molecule splits into two hydrogen atoms andone oxygen atom. These single atom forms of hydrogen and oxygen arehighly reactive and soon pair with one another to form diatomicmolecules of both hydrogen and oxygen.

Do non electrolytes dissociate in water?

This depends on the kind of dissociation: Salts, many acids and bases are electrolytes when dissociating inION's. On the contrary some dissociating molecules are non-electrolytes. By example hydrogen peroxide, dissolved in water, dissociates intotwo new non-ionic compounds (water and oxygen) so it i ( Full Answer )

What does water dissociate into-?

H"O dissociates into H+ + OH- . Note that the H+, a proton isactually present in aqueous solution as OH3+, O2H5+ , as itassociates with water molecules which are themselves hydrogenbonded together
