Reaction of metals with nitric acid |
|
Answer» Most of metals react with dilute acids to form salts and hydrogen gas (H2). Reaction of nitric acid with silver Ag + 2HNO3=AgNO3+NO2+H2O Reaction of nitric acid with sodium 2Na + 2HNO3=2NaNO3+H2 Reaction of nitric acid with magnesium Mg + 2HNO3=Mg(NO3)2+H2 Reaction of nitric acid with lead Pb + 2HNO3 =Pb(NO3)2 + H2 Reaction of nitric acid with potassium 2K + 2HNO3 = 2KNO3+ H2 Note = All metals do not liberate hydrogen gas during reaction with dilute because of their low reactivity power but they react with concentrated acids and form entirely different products.Ex - Copper (Cu) ,Silver (Ag) ,Gold (Au) etc... Nitric acid is a good oxidising agent .it oxidises hydrogen to form water Hydrogen gas must be liberate It will liberate hydrogen gas. Hydrogen gas must liberate |
