CBSE Class 10th Acid bases and salts

In this video we will learn about bases and their chemical properties.

• Bases are the chemical species which when dissolved in water furnish one or more hydroxide ions

• Base like NaOH reacts with active metal (Zn) to form a slat named as sodium zincate with liberation of hydrogen gas which highly combustible but non supportive in combustion 

2NaOH   +   Zn     →     Na2ZnO2   +   H2

• Base like NaOH reacts with non metallic oxide (SO2) to form the corresponding slat named as sodium sulfite and water. 

2NaOH   +   SO2     →     Na2SO3   +   H2O
