Is iron rusting to vinegar a physical or chemical change?
This is called rusting of iron. The process of rusting is represented as follows: Rusting of iron is a chemical change because a new substance iron oxide is formed. The presence of oxygen and water or water vapour is essential for rusting.
Is a rusty nail a chemical or physical change?
As the rust forms on the surface of the iron, it flakes off to expose more iron, which will continue to rust. Rust is clearly a substance that is different from iron. Rusting is an example of a chemical change.
What is physical change example?
Examples of physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.
What are 3 examples of physical changes?
A physical change is a change in appearance only. The matter is still the same after the change takes place. Examples of physical change include, cutting paper, melting butter, dissolving salt in water, and breaking glass.
Is hammering a nail a physical change?
Yes,hammering is a physical change since it does not change the chemical composition of a substance.
What happens when you mix vinegar and rust?
In your first experiment, the rust ($\\ce{Fe2O3. xH2O}$) probably reacted with vinegar to form Iron (III) acetate which makes the solution reddish in color. In your second experiment, the iron on the clean nail surface would have reacted with vinegar to form Iron (II) acetate.
What happens when you dip a rusty nail in veniger solution?
The F e X 3 + formed will react with the acetate ions to form red Iron (III) acetate. When you dip a rusty Iron Nail in veniger solution, the Viniger reacts with F e X 2 O X 3 ⋅ n H X 2 O (Rusty Iron or oxidized Iron).
Why does iron react with vinegar and acetic acid?
In your second experiment, the iron on the clean nail surface would have reacted with vinegar to form Iron (II) acetate. There are two main reasons why the solution might appear to have no change: Usually, Iron (II) acetate is prepared using concentrated acetic acid and scrap iron (or ferrous oxide/hydroxide).
What’s the difference between a clean and rusty iron nail?
When you dip a rusty Iron Nail in veniger solution, the Viniger reacts with F e X 2 O X 3 ⋅ n H X 2 O (Rusty Iron or oxidized Iron). Whereas in case of clean nail, Its directly reacts with iron. Your product is probably different due to this reason only, if I understood your question right.
