Q:

Is NH3 a strong base?

A:

Quick Answer

NH3 is not a strong base. A weak base is defined as a base that does not completely dissociate into ions when in a solution. Weak bases are also known as weak electrolytes and reactions with them are reversible.

Full Answer

Weak bases only react with water in a small amount when in a solution. When reacting with water, the weak base accepts H+ ions. However, the majority of the solution in a state of equilibrium consists of the unionized form of the base, with about 10 percent consisting of the hydroxide ions and the conjugate acid.

In contrast, a strong base, such as an alkali metal, will completely break down into ions when placed in a solution.

    What is a monoacidic base?

    A:

    According to Dictionary.com, a monoacidic base is a base that when dissolved in water produces one hydroxide ion or OH-, per molecule. In other words, a monoacidic base divides itself into two main components or molecules after reacting with water. One of the molecules is always a hydroxide ion and based on the definition of a monoacidic base, only one hydroxide ion is present.

    Is ammonia a strong base?

    A:

    Ammonia, a gaseous compound of one nitrogen atom bound to three hydrogen atoms, is not a strong base. It is a weaker base that generally must react with water before it reacts with an acid. Before it neutralizes acids in a solution, it reacts with water to form ammonium and hydroxide ions. Ammonium is a positive ion of one nitrogen and four hydrogen atoms, and it is a weak acid.
