- sodium chloride is not an acid
- in an acid solution the blue litmus paper become red
Litmus paper is a mixture of dyes that change color depending on the acidity or alkalinity of a solution. When exposed to sodium chloride, which is a neutral salt, litmus paper does not undergo a chemical reaction. It remains unchanged in the presence of sodium chloride.
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.
Sodium carbonate will turn red litmus paper blue. This is because sodium carbonate is a basic compound and can neutralize the acidity in the red litmus paper, causing it to change color.
Sodium chloride (NaCl) is a neutral salt and does not affect the pH of a solution, so it will not change the color of red litmus paper. Litmus paper changes color in response to the presence of acids or bases, but NaCl does not fall into either category and is therefore inert towards litmus paper.
Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.
Sodium chloride solution is neutral.

Sodium hydroxide turns red litmus paper blue.

Red litmus paper will not change color in the presence of sodium chloride. Sodium chloride is a neutral compound and does not have acidic or basic properties that would cause a color change in red litmus paper.
Sodium chloride (NaCl) is a neutral salt and does not affect the pH of a solution, so it will not change the color of red litmus paper. Litmus paper changes color in response to the presence of acids or bases, but NaCl does not fall into either category and is therefore inert towards litmus paper.
Hydrogen chloride turns damp blue litmus paper red.
Red to blue due to hydrolysis
Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.
Sodium hydroxide is a strong base and will turn red litmus paper blue. This color change occurs due to the high concentration of hydroxide ions present in the sodium hydroxide solution, which react with the indicator dye in the litmus paper, causing the color change.
As Lemon Juice is an Acid, the colour of the Red Litmus Paper will stay the same.
