A base is either an oxide or hydroxide; it is insoluble in water. There have been different definitions of a base; in simple terms, a base is defined as an electron-pair donor example of a base are sodium oxide, magnesium hydroxide, zinc oxide, and calcium hydroxide.
A base will react with an acid to produce salt and water; they are also electrolytes and aqueous solutions that turn red litmus paper to blue. A strong base is completely ionized in water; examples are NaOH, KOH. Examples of strong base reactions are KOH +H2O K + OH. The weak base is those that are slightly ionized in water. Examples of the weak base are Ca (OH) 2 and ammonia solution etc. examples of weak base reaction is
NH3 + H2O NH4OH
In chemistry, bases are referred to as proton acceptors. The strength of bases is to be classified into strong bases and weak base. Strong bases are completely ionized in water; they are strong electrolytes. Examples are KOH, NaOH, and Ba (OH)2. The pH of a strong base is usually between 10 and 14. They have a higher equilibrium constant and also highly reactive; they also have the ability to generate electricity.
Weak bases are those that are slightly or partially ionized in water. Examples are Ca (OH), Mg (OH), and ammonia solution, alanine, ethylamine, glycine, hydrazine. The solution of a weak base has a higher hydrogen ion concentration than the strong base. The pH of weak bases is always below 10. The weak bases are weak electrolytes and always weak electric conductivity.
In science and especially chemistry, there are acids and bases. Students usually study these in their science class. However, there are certain foods and things in nature that are more acidic than others. They may be strong in acid, but there may also be things that are weak in acid. That is not to say that they are not acidic if they are weak because they are.
The same can be said for bases. To determine if they are strong or weak and an acid or a base, the scientists will use a litmus test. There are fourteen numbers. Bases range from seven to fourteen. Strong bases will register as fourteen, and the weaker stations will record closer to seven on the litmus test.
