Bases are the opposite of acids due to the fact they are a hydrogen ion acceptor and an acid is a hydrogen ion donor.

In the many definitions of bases and acids, bases do the opposite of what acids do.

-- In the Lewis definition, acids are electron pair acceptors while bases are electron pair donors.

-- In the Bronsted-Lowry definition, acids are substances that donate protons while bases are substances that accepts protons.

-- In practicality, acids lower the pH of a solution and bases increase the pH of a solution.

A BASE is an oxide of a metal.

An ALKALI is a soluble base.

An acid can neutralise both. However, they are not seen as 'opposites'.

Remember the reactions of acids. ( low pH)

Acid + Alkali = Salt + Water (neutrality - pH 7)

Acid + Base = Salt + Water (neutrality - pH 7)

Acid + Metal = Salt + Hydrogen

Acid + Carbonate = Salt + Water (ph7) + Carbon Dioxide(Acidic gas)

From the table Acids and Alkalis/Bases neutralise one another producing a salt & water . Resultant pH is '7'.

NaOH + HCl -> NaCl + H2O

The reaction result, a salt and water. Is this what you meant?

What determines the strength of acids and bases?

The strength of acids and bases is most often indicated by the concentration of hydrogen ions in the solution. This is called the pH.
