Uses of Bases

There are various use cases of base, some of these are:

  • Sodium hydroxide is used in the manufacture of soap and paper. Sodium hydroxide (NaOH) is also utilized in the production of rayon.
  • Bleaching powder is made from Ca(OH)2, commonly known as slaked lime or calcium hydroxide.
  • Calcium hydroxide is used to create dry mixtures for painting and decorating.
  • Magnesium hydroxide, popularly known as milk of magnesia, is a laxative that is extensively used. It is also used as an antacid since it decreases excess acidity in the human stomach.
  • In laboratories, ammonium hydroxide is a critical reagent.
  • Slaked lime can be used to neutralize any excess acidity in soils.

What are Bases? – Definition, Examples, Types, Properties and Uses

Base is a chemical compound that consists of OH ions and accepts protons. Base in Chemistry are those compounds that turn red litmus blue and when reacted with acid they neutralize the reaction to give salt and water. The pH value of the base is greater than 7. Bases are bitter in taste and slippery in touch. The bases which are soluble in water are called Alkalis. Examples of Bases are Metal Oxides, Metal Hydroxides, etc. Soap is an example of a base that we use in daily life. In this article, we will learn about the definition, properties, and chemical reactions of Bases in detail.

Base Definition

Base is defined as the chemical compound whose pH value is greater than 7, accepts a proton, neutralizes acid, and turns red litmus to blue. They generally liberate OH– ion on dissociation. Examples include NaOH, NaHCO3, etc. Following are some general features shown by the base:...

Lewis Base

Lewis Bases are the compounds that have electron pair and they can donate it to the compounds which are deficient in electron pairs. Lewis Bases are Nucleophilic in nature i.e., they are nuclei-loving which means they will attack a positively charged centre with their electron pairs. Examples of Lewis Base include Ammonia because in Ammonia (NH3) the centre atom Nitrogen has 5 electrons out of which 3 is used in making bonds with 3 Hydrogen atoms and one pair of electrons remains left with the N atom thus making NH3 a Lewis Base....

Arrhenius Base

According to Arrhenius’s Concept, Bases are compounds that release hydroxide ions when dissolved in water and increase the concentration of hydroxyl ions in the aqueous solution. For Example, when KOH is dissolved in water it will give OH– ion and thus increase the concentration of OH– in the water....

Bronsted Base

Bronsted Concept of Base is an advanced version of Arrhenius’s Concept which states that bases are compounds that accept H+ ion or proton to form their conjugate acid. For Example Cl– is a base that accepts H+ to form HCl as its conjugate acid....
