in which test tube will the Iron nail Trust
Answers
Answer:
it will be Test tube A Only water I think
Answer:
In test tube A) the iron nail got rusted.
a)The corrosion of iron indicates a chemical change in the metal. Rust (hydrous oxide) is an example of this change that results when iron is exposed to water or damp air. ... Your iron nail will indeed rust more quickly and severely in salt water.
b)No, because distilled water has no dissolved oxygen in it.
c) Rust is an iron oxide formed by the reaction of iron and oxygen in the presence of water. Normal water (left) contains a high proportion of oxygen so this nail rusts the most. Anhydrous calcium chloride acts as a desiccant, removing moisture from the air and preventing the middle nail from rusting.
