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
