the reaction of the indicator is HIn+ H20 ->(H30 or H+ )+ In-
if say for instance NaCl were to be added The Na+H20 yields NaOH which you know simply doesnt happen because its ionic so they just float around. Cl part of it would want to react with the H+ so you would get H + Cl -> HCl in the total net reaction which doesn't happen because it is ionic so therefore it simply doesnt happen.
Salt water does not change the color of an object. However, if an object is fully submerged in salt water, it may appear slightly magnified due to the way light refracts through the water.
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).
Sand and salt can be separated using filter paper and a funnel because salt dissolves in water, while sand does not. When the mixture is added to water and stirred, the salt will dissolve, leaving the sand behind. By pouring the mixture through filter paper in a funnel, the sand is trapped on the paper while the salt solution passes through, allowing for the separation of the two components.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
The indicator is not used in this reaction because the reaction between an acid and potassium hydroxide is a neutralization reaction, where the acid and base completely react to form water and a salt. The endpoint is indicated by the formation of a solid precipitate or a color change due to the formation of the salt, so an indicator is not necessary.
THE COLOUR of the litmus paper will not change as a salt solution is neutral
When salt is mixed with a liquid indicator, it may not change color immediately. The liquid indicator's color change is usually due to a change in pH levels rather than the presence of salt. Salt does not typically cause a color change in liquid indicators.

Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
this is a chemical change cause you can't return it back to solid salt
How to change to salt water pool
Indicator is a process which is used to find out the substanceis acid,base and salt. example: litmus paper and termuric both are natural indicator. example of artificial indicator: mithyl orange and phenolphtaceil
You cannot do it with paper.

just water and salt
When salt is added to water to change its color, the salt dissolves in the water and does not directly affect the color of the water.
