If test chlorine with a moist blue litmus paper,
Turn from blue à red à colourless
It is because chlorine reacts with water (moisture on paper) to from HOCl (hypochlorite acid) which is a bleaching agent, turning the dye to colourless
Cl2 (aq) + H2O (l) à Hcl (aq) + HOCl (aq) and HOCl à HCl + [O]

What is the effect of carbon monoxide on moist litmus paper?
Carbon monoxide does not have a direct effect on moist litmus paper as it is not an acidic or basic gas. Litmus paper changes color in response to acidic or basic substances.
How does moist blue litmus paper reacts with dry HCl?
Moist blue litmus paper will turn red when it comes in contact with dry HCl. This is because the dry HCl gas dissolves in the moisture on the litmus paper to form hydrochloric acid, which turns the blue litmus paper red indicating an acidic solution.
What colour does moist red litmus paper turn in magnesium oxide?
Moist red litmus paper will turn blue when exposed to magnesium oxide because magnesium oxide is a basic compound. The red litmus paper will change color to blue to indicate the presence of a base.
Which gas turns moist starch iodide paper blue black?
Chlorine gas turns moist starch iodide paper blue-black.
Can Sulfur dioxide change the litmus color?
Yes, Sulfur dioxide turns moist litmus paper from blue to red.
What happens to blue litmus paper when you mixed it with MO?
As methyl orange is slightly acidic, it turns 'moist' blue litmus into red.
What is the effect of carbon monoxide on moist litmus paper?
Carbon monoxide does not have a direct effect on moist litmus paper as it is not an acidic or basic gas. Litmus paper changes color in response to acidic or basic substances.
What effect does chlorine have on moist universal indicator?
Chlorine turns moist universal indicator paper red, then bleached. It has the same effect on blue litmus paper (red then bleached). this shows it is an acidic gas and so when reacts with sodium for example (an alkali metal) makes sodium chloride (salt).
What happens when moist blue litmus paper is place in a jar containing carbon dioxide?
When moist blue litmus paper is placed in a jar containing carbon dioxide, it turns red. This occurs because carbon dioxide dissolves in the moisture of the paper, forming carbonic acid, which lowers the pH. The resulting acidic environment causes the blue litmus paper to change color, indicating the presence of an acid.
What colour does nitrogen turn moist red litmus paper?
Nitrogen gas (Nā) does not change the color of moist red litmus paper. This is because nitrogen is a neutral gas that does not have acidic or basic properties. Therefore, it will not cause any color change in the litmus paper.
How does moist blue litmus paper reacts with dry HCl?
Moist blue litmus paper will turn red when it comes in contact with dry HCl. This is because the dry HCl gas dissolves in the moisture on the litmus paper to form hydrochloric acid, which turns the blue litmus paper red indicating an acidic solution.
What gas is produced when moist blue litmus turn red?
When moist blue litmus paper turns red, it indicates the presence of an acidic gas such as carbon dioxide (CO2) or sulfur dioxide (SO2). This change in color is due to the acidification of the blue litmus paper by the acidic gas.
What colour does moist red litmus paper turn in magnesium oxide?
Moist red litmus paper will turn blue when exposed to magnesium oxide because magnesium oxide is a basic compound. The red litmus paper will change color to blue to indicate the presence of a base.
Why must litmus paper used to observe gas be moist?
Litmus paper is used moist to obtain the desired result. Litmus responds different to dry and wet conditions depending on the chemicals being checked.
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.
Which gas turns moist starch iodide paper blue black?
Chlorine gas turns moist starch iodide paper blue-black.
Can Sulfur dioxide change the litmus color?
Yes, Sulfur dioxide turns moist litmus paper from blue to red.
