To explain how a substance dissociates to produce ions in solution, consider a typical ionic compound, such as sodium chloride (NaCl). When NaCl is dissolved in water, the polar water molecules interact with the sodium ions (Na⁺) and chloride ions (Cl⁻), effectively pulling them apart and allowing them to disperse throughout the solution. This process results in the Na⁺ and Cl⁻ ions becoming free to move independently, thus conducting electricity and creating an electrolyte solution. Other ionic compounds will follow a similar dissociation process, depending on their specific chemical structure.
No, zero conductivity does not necessarily mean that a substance is a non-electrolyte. It means that the substance does not conduct electricity. A non-electrolyte is a substance that does not dissociate into ions in solution and therefore does not produce any charged particles to carry an electric current.
A substance that yields an anion plus the hydroxyl ion in water is a strong base. Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH) which dissociate completely in water to produce hydroxide ions.
No, a substance that produces ions in water is not a non-electrolyte; it is classified as an electrolyte. Electrolytes are substances that dissociate into ions when dissolved in water, allowing them to conduct electricity. In contrast, non-electrolytes do not produce ions in solution and therefore do not conduct electricity.
An example of a substance that ionizes completely in aqueous solutions to produce H3O+ ions is hydrochloric acid (HCl). When dissolved in water, HCl dissociates into H+ and Cl- ions, with the H+ ions combining with water molecules to form hydronium ions (H3O+).
Strong because a substance with a pH of 7 is considered neutral, so the further away from 7 the pH gets, the more strong of an acid it becomes.
Bases dissociate to produce hydroxide (OH-) ions

Strong bases dissociate or ionize completely. Weak bases dissociate or ionize only partially. The degree to which they ionize/dissociate is given by the Kb for each weak base.

Ionic compounds can dissociate into ions when dissolved in water. Common examples include sodium chloride (NaCl), potassium nitrate (KNO3), magnesium sulfate (MgSO4), and calcium chloride (CaCl2).
Two strong bases are sodium hydroxide (NaOH) and potassium hydroxide (KOH). These bases dissociate completely in water to produce hydroxide ions, contributing to high pH levels in solutions.
The strength of an acid or a base in water is determined by the extent to which it dissociates into ions. Strong acids and bases completely dissociate in water to produce a lot of ions, making them strong electrolytes. Weak acids and bases only partially dissociate, producing fewer ions and making them weak electrolytes.
Svante Arrhenius' concept of acids and bases, proposed in 1884, defined acids as substances that dissociate in water to produce hydrogen ions (H+) and bases as substances that dissociate in water to produce hydroxide ions (OH-). He proposed that a substance's ability to form ions in solution determined whether it was an acid, base, or neutral. This theory laid the foundation for modern theories of acids and bases.
