Answer 1

Answer:

Chemical Properties of Bases

• Bases change the colour of litmus from red to blue.
• They are bitter in taste.
• Bases lose their basicity when mixed with acids.
• Bases react with acids to form salt and water. This process is called Neutralisation Reaction.
• They can conduct electricity.
• Bases feel slippery or soapy.
• Some bases are great conductors of electricity.
• Bases like sodium hydroxide, potassium hydroxide, etc are used as electrolytes.
• Alkalis are bases that produce hydroxyl ions (OH-) when mixed with water.
• Strong alkalis are highly corrosive in nature whereas other alkalis are mildly corrosive.
• The pH value of bases ranges from 8-14.
• Alkalis and ammonium salts produce ammonia.
• Hydrogen gas is evolved when metals react with a base.
• Bases are classified on the basis of strength, concentration and acidity.
• The different kinds of acids are strong base acid, weak base acid, concentrated base, dilute base, monoacidic base, diacidic base and triacidic base.
