Small pieces of steel and some powdered rust are taken in two test tubes separately. What will you obseve when concentrated hydrochloric acid is poured into both the test tubes ? Justify your observation. |
| Answer» SOLUTION :Steel is an alloy, i.e., a mixture in which iron is the major component and it retains its property in steel. Hence, PIECES of stell will liberate hydrogen and effervescence will be observed. However, rust being a compound of iron does not exhibit the chemical property of iron. Rust dissolves in hydrochloric and due to the formatio ferric CHLORIDE and no effervescence will be observedin that test tube. | |
