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...
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. ...
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 ...
Forum: Chemistry N When to Use Kw & Ka for Acid Dissociation Calculations So I've learned that in strong acids that dissociate completely, the concentration of H+ is the same as the concentration of the initial solution. So 1M of a strong acid will create 1M of H+, meaning the pH ...
An electrolyte is a chemical compound that, in solution or in the molten state, dissociates into ions and conducts an electric current. On passing an electric current from an external source. More About Electrolyte The ions in the electrolyte migrate towards the oppositely charged electrodes. Posit...
Dissolving salt in water creates a solution (i.e., a homogeneous mixture) of the solute salt (NaCl) in the solvent water (H2O). During dissolution, the salt grains break apart (i.e., dissociate) to form charged particles (Na+ and Cl−) in solution. These charged particles are called...
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 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...
