When fluorine gas is exposed to damp blue litmus paper, it will react with the water present on the paper to form hydrofluoric acid (HF). Hydrofluoric acid is a weak acid that will turn the blue litmus paper red, indicating an acidic solution. This reaction occurs because fluorine is a highly reactive element that readily reacts with water to form acids.
Oh, dude, when fluorine meets damp blue litmus paper, it's like a bad blind date. The fluorine gets all excited and starts reacting with the water in the damp paper, creating hydrofluoric acid. So, yeah, basically, the blue litmus paper turns red because of the acidic reaction. Chemistry, man, it's wild.
Fluorine is a highly reactive element that will react with water vapor in the air to form hydrogen fluoride. When hydrogen fluoride comes into contact with damp blue litmus paper, it will turn red due to the acidic nature of hydrogen fluoride.
When chlorine comes in contact with litmus paper it bleaches it, so it turns white. Before it turns white, though, it can turn pink because of the acids formed when chlorine reacts with water. Cl2 + H2O -> HOCl + HCl
Not sure about the effect of other halogens on damp, blue litmus paper, but I suspect that similar reactions would occur.
It turns red after fluorine has reacted to formation of (some) hydrofluoric acid.

How does litmus paper react when exposed to vinegar?
Litmus paper turns red when exposed to vinegar because vinegar is acidic. Litmus paper is a pH indicator that changes color in response to the acidity or alkalinity of a solution.
What colour does litmus paper turn with common salt?
Litmus paper turns red when exposed to an acidic solution and blue when exposed to a basic solution. Common salt (sodium chloride) is neutral, so it does not significantly change the color of litmus paper.
Why would litmus paper turn green?
Litmus paper turns green when it is exposed to a substance that is close to neutral on the pH scale, typically around pH 7. This change indicates that the solution is neither acidic (which turns litmus paper red) nor basic (which turns litmus paper blue).
What kind of litmus paper do you use if you have an acid?
You would use red litmus paper for an acid. Red litmus paper turns blue in the presence of a base, so if it remains red when exposed to a solution, it indicates that the solution is acidic.
What color does litmus paper turn in sugar?
Litmus paper will not change color when exposed to sugar because sugar is neutral and does not alter the pH level of a solution. Litmus paper changes color based on the acidity or alkalinity of a substance.
How does litmus paper react when exposed to vinegar?
Litmus paper turns red when exposed to vinegar because vinegar is acidic. Litmus paper is a pH indicator that changes color in response to the acidity or alkalinity of a solution.
What happens to red litmus paper if dipped in vineger?
Sour milk is acidic. Red litmus paper should not change.The sour part of sour milk is lactic acid. As litmus paper turns red when exposed to acidic compounds, litmus paper that is already red should not react when exposed to lactic acid.
What colour does fluorine turn blue litmus?
Fluorine does not have a specific color reaction with blue litmus paper, as it does not change the color of the paper. However, fluorine gas is highly reactive and can potentially react with the water in the litmus paper, causing bleaching or other color changes.
What happens to litmus paper when water is added?
litmus paper nutral
What does a base do to red litmus paper?
Red litmus paper is used to check for basicity. It turns blue when exposed to bases. Blue litmus paper is used to check for acidity. It turns red when exposed to acids.
What colour does litmus paper turn with common salt?
Litmus paper turns red when exposed to an acidic solution and blue when exposed to a basic solution. Common salt (sodium chloride) is neutral, so it does not significantly change the color of litmus paper.
What color does does litmus paper turn when exposed to a base?
blue
What color is blue litmus paper when exposed to an acid?
Blue litmus become red in acidic solutions.
Why would litmus paper turn green?
Litmus paper turns green when it is exposed to a substance that is close to neutral on the pH scale, typically around pH 7. This change indicates that the solution is neither acidic (which turns litmus paper red) nor basic (which turns litmus paper blue).
How pH paper distinguishes acid and bases?
pH paper changes color after being exposed to an acidic or a basic solution (depending on the paper). For instance, blue litmus paper will turn red after being exposed to an acidic solution, while red litmus paper will turn blue after being exposed to a basic solution. The addition of an acidic or basic solution to litmus paper causes a chemical reaction which changes the light absorbing properties of litmus, thus altering its color.
What happens to red litmus paper when it is placed in an acid?
Nothing - red litmus paper indicates the presence of bases.
What happens if hydrochloric acid is experimented on red litmus paper?
Red litmus paper is used for alkaline solutions.
