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 chloride is not an acid - in an acid solution the blue litmus paper become red
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.
Barium nitrate is a salt that is neutral in pH, so it will not cause a significant color change in red litmus paper. The litmus paper will likely remain red or may show a very slight color change due to impurities in the sample.
Litmus at a pH of 7 (which is nominally what an NaCl solution should have at room temperature) is a kind of purple color, somewhere between the "red" acidic form and the "blue" basic form. As with many indicators, the color change happens over a range rather than at a specific pH; the range for litmus is from around 5 (red) to 8 or so (blue).
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.
sulphuric acid colour on pH paper
THE COLOUR of the litmus paper will not change as a salt solution is neutral
it will change into red colour
- sodium chloride is not an acid - in an acid solution the blue litmus paper become red
Barium nitrate will not change the color of blue litmus paper. It is a neutral salt and does not produce an acidic or basic solution when dissolved in water. Therefore, blue litmus paper will remain blue when exposed to a barium nitrate solution.
Acids turn the red litmus paper blue. Is salt a typeof acid??

The red litmus paper will not change color when placed in table salt and water because salt (sodium chloride) is a neutral substance. Litmus paper changes color in response to acidic or basic solutions, not neutral ones.
Litmus paper doesn't "do anything" to a solution. Litmus paper has some dyes on it, so some of the dyes might leak into the solution though. NaCl won't do anything to Litmus paper either. Salt, when dissolved in water, maintains a neutral solution. Litmus paper only changes color when there is a pH change. So, nothing really will happen.
