What are bases? Give example.
Answers
Examples of bases are sodium hydroxide, calcium carbonate and potassium oxide. A base is a substance that can neutralize the acid by reacting with hydrogen ions. Most bases are minerals that react with acids to form water and salts. ... Sodium hydroxide is an alkali.
Explanation:
Bases are substances that slippery to touch when in aqueous form. They taste bitter and change the color of red litmus paper to blue. Bases also dissociate in the water like acids, but instead of producing H+ they produce OH- i.e. hydroxyl ion. If a base dissolves in water then it is called an Alkali. Ammonium hydroxide, Calcium hydroxide are some examples of alkalis. Alkalines become less alkaline when mixed with acids. The pH level of bases ranges from 8-14.
Some examples are caustic soda or sodium hydroxide, calcium hydroxide or limewater, borax. A lot of bleaches, soaps, detergents, kinds of toothpaste, etc are bases.
