What happens when moist blue litmus paper dipped in chlorine?
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]
If red litmus is added to a alkali?
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
What gas turns blue litmus paper red?
An acid solution turns blue litmus red.
What substance in litmus paper helps in its change?
It depends. Litmus paper is used to test pH levels. Blue litmus paper turns red in the presence of acids, and red litmus paper turns blue in the presence of alkalines. Litmus paper is purple in neutral conditions.
What are litmus paper?
Litmus is a natural dye indicator extracted from lichens.They react with acid (blue litmus turns red)& bases(red litmus turns blue) .Paper made with litmus dye indicators are called litmus paper and used in chemical laboratories.
What do you see when chlorine is put with litmus or universal indicator paper?
When chlorine gas reacts with litmus paper, it will turn red litmus paper white and then dissolve it. When chlorine gas reacts with universal indicator paper, it will change the color to yellow due to its acidic nature.
What happens when moist blue litmus paper dipped in chlorine?

Which Brown gas bleaches damp litmus paper?
Chlorine gas in combination with water can bleach damp litmus paper. The reaction between chlorine gas and water forms hydrochloric acid and hypochlorous acid, which are powerful bleaching agents that can react with and bleach the litmus paper.
What is the test for Chlorine Gas?
One test for chlorine gas is using starch-iodide paper, which turns blue in the presence of chlorine gas due to the formation of the triiodide ion. Another test involves the reaction of chlorine gas with damp litmus paper, which is bleached, turning it white. Additionally, the distinctive smell of chlorine gas can also be used to identify its presence.
If red litmus is added to a alkali?
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
Is turning litmus paper red from blue a chemical change?
Yes, turning litmus paper red from blue is a chemical change because the color change results from a chemical reaction between the litmus paper and the substance it comes into contact with, indicating a change in the chemical composition of the paper.
What gas turns blue litmus paper red?
An acid solution turns blue litmus red.
How can you distinguish between sulfur dioxide and chlorine using blue litmus paper?
Sulfur dioxide will turn blue litmus paper red, indicating acidity due to the formation of sulfurous acid. Chlorine will not produce any color change in blue litmus paper as it is neither acidic nor basic.
What colour does red litmus paper go when it rains?
Red litmus paper does not change color when it rains; it remains red. Litmus paper is used to test pH levels, and rainwater is typically neutral to slightly acidic, which does not affect the color of red litmus paper. The color change occurs when red litmus paper is exposed to a basic (alkaline) solution, turning blue.
What substance in litmus paper helps in its change?
It depends. Litmus paper is used to test pH levels. Blue litmus paper turns red in the presence of acids, and red litmus paper turns blue in the presence of alkalines. Litmus paper is purple in neutral conditions.
What happens to red litmus paper if dipped in water?
Red litmus paper remains red when dipped in water. Litmus paper is used to test for acidity or basicity, and red litmus paper turns blue in basic solutions. If the water being tested is neither acidic nor basic, the red litmus paper will not change color.
What color litmus paper is used to test acids?
Red litmus paper is used to test for acids. If the red litmus paper turns blue when dipped in a substance, it indicates the presence of an acid.
