Dry cleaners use a combination of detergents and solvents to clean a wide array of fabrics. Certain detergents or solvents must be used on particular fabrics to avoid shrinking or discoloration.
I'm not quite sure. But it must be something strong.(:
the only one i know of is bleach. buy at a grocery store
Carbon tetrachloride, which is used in dry cleaning. No longer available for household use.
chlorine
phisical, unless using bleach. bleach actually changes pigment, while normal dye just covers-up the existing color.
No, bleach changing the color of a shirt is a chemical change. The active ingredient in bleach, sodium hypochlorite, reacts with the dyes in the fabric, breaking them down and removing their color. This results in a permanent change in the chemical composition of the fabric.
chemical !!! obviously.......
Pouring tang into water is a chemical change. A change a said to be chemical if it changes color, taste, volume etc. Pouring tang into water causes a chemical change because the color changes and the volume of the tang changes because it is in a liquid state.
It changes the sugar's color
It is bleached by the ultraviolet rays in the sunlight.

Color and density are physical properties, not changes.

When bleaching your shirt it is a chemical change.
Bleach is a mixture of water and sodium hypochlorite, and is commonly used as a disinfectant or 'bleaching agent', or removing color and whitening. The chemical formula for Sodium Hypochlorite is NaClO.
An oxidizing bleach works by breaking the chemical bonds of a chromophore (part of a molecule that has color). This changes the molecule so that it either has no color or else reflects color outside the visible spectrum. A reducing bleach works by changing the double bonds of a chromophore into single bonds. This alters the optical properties of the molecule, making it colorless.

- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.
Bleaching your hair is a chemical change. The bleach reacts in hair, removing the color in an irreversible chemical reaction. There is no way to reverse the bleaching. Bleaching your hair also makes a new substance, when you do bleach your hair it is permanent.
