Acid/Base Concept
Bases are ionic substances that dissolve in water to form negative hydroxide (OH) ions. However, what are ions? Ions are atoms that acquire or lose electrons, causing them to change into charged particles. Sodium hydroxide, or NaOH, is an illustration of a base. It releases sodium (Na+) ions and negative hydroxide (OH) ions when it dissolves in water. The following equation serves as a representation of it:
NaOH →H2O + OH− + Na+
Acid/Base Concept | Acid Properties | Base Properties |
Arrhenius | Gives H+ in an aqueous medium. | Gives OH- in an aqueous medium. |
Lewis | Accepts electrons lone pair. | Donates electrons lone pair. |
Bronsted-Lowry | Gives out H+. | Accepts H+. |
Summary:
Bases are ______ in taste. (a) Salty (b) Sweet (c) Bitter (d) Sour
Bases have a bitter flavor whereas acids have a sour flavor. An ionic compound is one that is kept together by an ionic bond and contains both a positive metal ion and a negative nonmetal ion.
