What colour does red litmus paper turn in bleach?
blue
Bleach is chemically known as sodium hypochlorite. The pH of bleach is approximately 11, a strongly alkaline, or basic, solution. Placed on red litmus paper, it will turn it blue.
What does it mean if litmus paper is bleached?
Chemical reactions other than acid–base can also cause a color change to litmus paper. For instance, chlorine gas turns blue litmus paper white; the litmus dye is bleached because hypochlorite ions are present. This reaction is irreversible, so the litmus is not acting as an indicator in this situation.
What happens when red litmus paper is dipped in chlorine water?
Chlorine gas bleaches the damp litmus (red or blue). Bleaching is an oxidation process. If you are considering the colour change only – refer to it as bleaching.
What happens when a red litmus paper is dipped into an acid solution?
When a red litums paper is dipped in an acidic solution, it does not have any effect on it. If it is base, Then only it can turn it into blue colour.
Does chlorine bleach red litmus?
Chlorine gas reacts with water to produce an acidic solution which is also an effective bleach. The acidic solution formed on the damp litmus paper turns the indicator red. Then the bleach turns the red colour to white.
Why does litmus paper turn red?
Litmus Test Chemistry It’s because of 7-hydroxyphenoxazone. When exposed to acids below pH 4.5, the molecule looks like the image below and this gives litmus paper its red color. As the pH of the test solution moves towards alkaline, one of the hydrogen atoms (white hemispheres) starts to break off (disassociate).
Does chlorine bleach red litmus paper?
Why does chlorine bleach litmus paper?
For instance, chlorine gas turns blue litmus paper white – the litmus dye is bleached, because of presence of hypochlorite ions. This reaction is irreversible, so the litmus is not acting as an indicator in this situation.
When the red litmus paper is dipped in lemon juice?
Answer: red litmus paper when in lemon juice will be the same because it is acidic and acidic turn into red.
What happens if red litmus paper stays red?
