Sodium hydroxide (NaOH) is a classic example of a strong base because it produces hydroxide (OH-) ions and dissociates completely in water. Ammonia is an example of a weak base because it is a proton acceptor.
There are two accepted definitions of bases.
The more usual is the Bronsted-Lowry definition: a base is a species which can accept a proton (hydrogen ion).
The Lewis theory is of wider application (though it would only be used in more advanced work) and defines a base as an electron pair acceptor.
a solution whose pH level is greater than 7 (pure water is very close to 7, and is considered to be neutral). A link to a very good explanation is below.
A base is any solution with a pH greater than 7 (pure water). Bases are slippery, bitter, and include things such as soaps, eggs, and blood.
Water is neutral.
But technically it is an amphoteric substance, meaning it can act as both an acid and a base. However, it is very weak in both respects.
