Question

What is the strongest alkali?

Answer 1

Hint: strongest alkali is sodium hydroxide. It is an alkali metal. It lies in group one of the periodic table. It can neutralize acids. It turns red litmus blue. It is corrosive to plant and animal tissues. Alkalis are the ones that can be soluble in water. They are also called bases. They dissociate completely in water.

Complete answer:
Alkalis are soluble hydroxides of alkali metals. Alkali metals make up a group $1$ of the periodic table. They are the bases that are soluble in water. For example Sodium hydroxide, Potassium hydroxide, etc. They are soluble salts that easily dissolve in water and dissociate into ions. They have a bitter taste and they feel soapy and slippery on the touch. Their pH value is greater than$7$. And they turn red litmus paper to blue. They are caustic and in concentrated form are corrosive to organic tissues.
When alkalis react with an acid they undergo a neutralization reaction and form salt and water, and so they are the ones that can neutralize acids. When a mixture of alkali and ammonium salt is heated ammonium gas is produced. Solutions of alkalis are used to precipitate insoluble metal hydroxides from solutions of their salts.
Among all the alkalis the strongest alkali is sodium hydroxide\[\left( {NaOH} \right)\]. It is the toughest base of all the bases. When dissolved in water sodium hydroxide fully dissociates to give sodium ions and hydroxide ions. It is also known as caustic soda. When it is dissolved in water a large amount of heat is produced. The dissolution is highly exothermic. Its pH changes with normality but lies between $12 - 14$ which makes sodium hydroxide highly basic.

Note:
Whenever dealing with strong bases or even acids utmost care needs to be taken. It is important to note that whenever you mix acid or base with water, never add water to these solutions. Always add these solutions in water slowly. Because if you add water to these strong bases or acids then it can directly splash on your face, causing harm to your face. It may even burn.
