Why does bleach turn color items white or yellow?
Bleach contains chemicals that break down the pigments in colored items, making them appear white. However, if the colored item contains dyes or pigments that are not affected by bleach, it may still react and turn yellow due to oxidation.
What colour will bleach turn if it tested with universal indicator?
Bleach typically turns a greenish-yellow color when tested with universal indicator due to its high pH level. This indicates that bleach is a strong base.
Why would chlorine bleach turn cotton yellow?
Chlorine bleach can react with natural fibers like cotton and break down the fibers, causing them to weaken and appear yellow. This discoloration is often irreversible and can occur when the bleach is left on the fabric for too long or used in excessive amounts.
Why has the silver turned yellow?
Silver can turn yellow due to a chemical reaction with sulfur compounds in the air or on the skin, causing tarnishing.

Why does bleach turn yellow when mixed with red cabbage juice?
Bleach turns yellow when mixed with red cabbage juice due to the chemical reaction between the bleach (sodium hypochlorite) and the pigments in the cabbage juice, primarily anthocyanins. These pigments are sensitive to pH changes and can change color in response to different chemical environments. When bleach is introduced, it alters the pH and oxidizes the anthocyanins, resulting in a yellow hue. This color change is a visual indication of the chemical transformation occurring in the mixture.
What causes liquid bleach to go black?
Liquid bleach can turn black when it reacts with certain metals, such as iron or manganese that may be present in water or in the container.
