Why do all substances containing OH- ions are considered as bases?

∙ 12y ago
The definition of an Arrehnius base is an ionic compound that contains more OH- ions than H+ ions when dissolved in water.
The Bronsted-Lowry (more general) definition of a base is any substance that readily recieves protons. OH- ions very easily recieve protons (H+) to become H2O.

Substances such as NaOH which dissociate into OH- ions are classified as?
BASES!
What are they definition salt acid bases?
Acids are substances that produce hydrogen ions when added to water. Bases on the other hand will produce negative ions when added to water. Salts are formed as a mixture of acids and bases with the acids producing H+ ions and bases OH- ions.
Why are some substances acids while others are bases?
it depends on the concentration of ions
What types of ions do bases contain?
Bases have a high concentration of OH- in solutions. Substances like NaOH and KOH are strong bases.
What does a base in water produce?
Arrhenius defined bases as substances that dissolve in water to release hydroxide ions (OH-) into solution.
Substances that combine with hydrogen ions are called?
Bases

What substances in creases the number of H3O when dissloved in water?
An acid (containing dissociable H+ ions
How are acids and antacids opposite?
Acids are the substances which release hydrogen ions in solution while antacids are the substances which neutraliae the hydrogen ions so formed by the acids. Antacids are bases, and release hydroxide (OH) ions which combine with the (H) ions of the acids, forming water and salts.
Is it possible for an atom to be not neutral?
Yes, an atom that is not neutral (that is, it is either positive or negative) is referred to as an ion. Ions containing MORE protons than electrons are considered "positive". Ions containing LESS protons than electrons are considered "negative".
Why are acids and bases considered strong?
They either have a high concentration of H+ ions (acids) or OH- ions (bases). Strong acids and bases are also highly corrosive relative to weaker more neutral acids/bases.
Does calcium oxide have 2 ionic substances?
Calcium oxide is a single ionic substance made of two different ions. Calcium oxide (Ca2+) and oxide ions (O2-). But the two different ions are generally not considered substances in and of themselves.
What can alaminium oxide bond with?
Aluminium oxide, Al2O3, alumina, is an amphoteric oxide. It is not very reactive, but does react with acids and bases. It dissolves in acids. With bases it can forms aluminates containing polyatomic anions containing aluminium. ions.
What does a base in water produce?
Arrhenius defined bases as substances that dissolve in water to release hydroxide ions (OH-) into solution.
