Dry HCl gas does not change the color of dry litmus paper because HCl gas is not a strong enough acid to react with the litmus paper. Litmus paper is more sensitive to stronger acids.
An acid turns blue litmus paper red. This is because the acid donates a proton (H+) to the water in the litmus paper, changing the pH and causing the litmus paper to change color.
Acid turns litmus paper red.
True. Acids will turn litmus paper red due to the presence of hydrogen ions, which react with the dye in litmus paper and cause it to change color.

an acid
Acid rain will turn blue litmus paper red, indicating that the solution is acidic. Acid rain is characterized by an increased concentration of hydrogen ions, which react with the 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.
Dry HCl gas does not change the color of dry litmus paper because HCl gas is not a strong enough acid to react with the litmus paper. Litmus paper is more sensitive to stronger acids.
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.
An acid turns blue litmus paper red. This is because the acid donates a proton (H+) to the water in the litmus paper, changing the pH and causing the litmus paper to change color.
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.
True. Acids will turn litmus paper red due to the presence of hydrogen ions, which react with the dye in litmus paper and cause it to change color.

Red litmus paper contains a pigment that changes color in response to changes in pH. In acidic conditions, the pigment in red litmus paper turns red because the hydronium ions in the acid react with the pigment. In basic conditions, the pigment does not change color because the hydroxide ions in the base do not react with the pigment.
