An acid is a chemical species that donatesprotonsorhydrogenionsand/or acceptselectrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and...
3.dissociate- to undergo a reversible or temporary breakdown of a molecule into simpler molecules or atoms; "acids dissociate to give hydrogen ions" chemical science,chemistry- the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties ...
1. The act of dissociating or the condition of having been dissociated. 2. Chemistry a. The process by which the action of a solvent or a change in physical condition, as in pressure or temperature, causes a molecule to split into simpler groups of atoms, single atoms, or ions. b. ...
Stirring sugar into water is an example of dissolving. The sugar is the solute, while the water is the solvent. Dissolving salt in water is an example of dissolution of an ionic compound. The sodium chloride (salt) dissociates into sodium and chloride ions when it is mixed with water. Rel...
Bases may be categorized according to their degree of dissociation in water and reactivity. Astrong basecompletely dissociates into its ions in water or is a compound that can remove a proton (H+) from a very weak acid. Examples of strong bases include sodium hydroxide (NaOH) and potassium ...
An electrolyte is achemical compoundthat dissociates into ions and hence is capable of transporting electric charge - i.e. an electrolyte is an electric conductor; unlike metals the flow of charge is not a flow of electrons, but is a movement of ions. ...
Definitions of dissociation noun the act of removing from association see more noun a state in which some integrated part of a person's life becomes separated from the rest of the personality and functions independently synonyms: disassociation see more noun (chemistry) the temporary or ...
Chemistry. to cause (a complex substance) to resolve or decompose into its simpler constituents as a result of a change in physical conditions: UV radiation dissociates NO2 into NO (nitrogen monoxide) and O (atomic oxygen). to cause (a constituent of a complex substance) to separate from ...
As temperature increases, the degree of dissociation of water increases. Thus, the water dissociates to give more [H+], and hence its pH decreases. Temperature plays a significant role in pH measurements. As the temperature rises, molecular vibrations increase which results in the ability of wat...
In the field of chemistry, an acid is a substance that dissociates in water to yield H3 O+, has H in its formula, and has a higher H+ concentration in a solution. A base is a substance that dissociates in water to yield OH-, has OH in its formula, and would have a lower H+...
