Find out the chemical properties of metals with reaction with acid
Asked by amanbhargava | 19th May, 2010, 04:30: PM
Expert Answer:
Metal reacts with dilute acids to form metal salt and hydrogen gas.
| Metal | Reaction with acid | Equation | |
| Sodium (Na) | Sodium reacts violently with dil HCl | 2Na+2HCl 2NaCl+H2 |
|
| Magnesium (Mg) | Magnesium reacts rapidly with dil HCl |
Mg+2HClMgCl2+H2 |
|
| Zinc (Zn) | Zinc reacts less rapid than Mg |
Zn+2HClZnCl2+H2 |
|
| Iron (Fe) | Iron reacts slowly with dil HCl |
Fe+2HCl |
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 and itself gets reduced to any of the nitrogen oxides (N2O, NO, NO2). But magnesium (Mg) and manganese (Mn) react with very dilute HNO3 to evolve H2 gas.
