Detailed explanation-1: -Bases taste bitter, feel slippery, and conduct electricity when dissolved in water. Indicator compounds such as litmus can be used to detect bases. Bases turn red litmus paper blue. The strength of bases is measured on the pH scale.
Detailed explanation-2: -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. Bases include the oxides, hydroxides and carbonates of metals. The soluble bases are called alkalis. Sodium hydroxide is an alkali.
Detailed explanation-3: -Bases are another group of compounds that can be identified by their common properties. A base tastes bitter, feels slippery, and turns red litmus paper blue.
Detailed explanation-4: -Hint :A base is a substance which has a characteristic bitter taste, is slippery to touch, changes the colour of litmus from red to blue, has a pH greater than 7 and reacts with acids to undergo neutralization reaction.
