Question
A chemical compound having smell of chlorine is used to remove yellowness of white clothes in laundries.
Solution
The chemical compound you're referring to is likely Sodium Hypochlorite, commonly known as bleach. It has a strong smell that can be similar to chlorine. Here's how it works to remove yellowness from white clothes:
-
When clothes are washed in bleach, the bleach dissolves into the water and breaks down into its basic components. One of these components is a type of molecule called a hypochlorite ion.
-
These hypochlorite ions can penetrate the fabric of the clothes and break down the molecules that are causing the yellow stains. These stain molecules are usually organic compounds, and the hypochlorite ions are able to break the bonds that hold these compounds together.
-
Once the bonds are broken, the stain molecules are no longer able to absorb light and appear colored. Instead, they either reflect light or let it pass through, which makes the fabric appear white again.
-
After the washing cycle is complete, the leftover bleach and broken down stain molecules are rinsed away with water.
-
The smell of chlorine is due to the presence of hypochlorite ions. The smell usually dissipates after the clothes are rinsed and dried.
