The chemical properties of acids 

• Acids change the colour of litmus from blue to red.
• They convert the colour of Methyl Orange from Orange/Yellow to Pink.
• Acids turn the pink colour of Phenolphthalein to colourless.
• Acids can conduct electricity.
• Some Acids are highly corrosive in nature which means that they corrode or rust metals.
• Acids tend to evolve hydrogen gas whilst reacting with an active metal such as Zn, Mg, etc.
• They produce H+ ions when mixed with water.
• Acids lose their acidity when mixed with a base.
• When equal amounts of acid and base are combined the process of neutralization occurs and salt and water is formed,
• The pH value of acid is from 0-6. Learn the concept of pH value here.
• Acids are sour in taste.
• Acids react with carbonates and hydrogen carbonates to form a salt, water, and carbon dioxide gas.
• Extremely active metals such as Potassium (K), Calcium (Ca), Sodium (Na), etc tend to explode when combined with acids.

In the chemical properties of  bases 

• 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(Read).
• 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.
