In this Chemistry video in Hindi for Class 10 we explained one of the chemical properties of metals. We discussed on how metals react with acids.
Metal + Dilute acid → Salt + Hydrogen
But, hydrogen gas is not evolved when a metal reacts with nitric acid. It is because HNO₃ is a strong oxidising agent. It oxidises the H₂ produced to water.
But magnesium (Mg) and manganese (Mn) react with very dilute HNO₃ to evolve H₂ gas. Because, these are strong reducing agents and reduces H₂O into H₂
