Litmus paper turns purple in neutral solutions because it contains a pH-sensitive dye that changes color based on the acidity or alkalinity of the solution. In neutral conditions, with a pH around 7, the dye in litmus paper exhibits a purple color due to the balance of hydrogen and hydroxide ions. This color change indicates that the solution is neither acidic nor basic.

What color does litmus blue and red paper turn in acid?
im thinking it would turn red:)
What color does acids turn red litmus paper?
i think purple Acid does not change the color of red litmus paper.
Why does litmus turn purple?
Litmus paper turns purple in a basic solution due to a chemical reaction with hydroxide ions in the solution. The dye in litmus paper undergoes a change in structure when it comes in contact with a base, causing it to reflect purple light.
What colour would water turn if you added litmus?
I think it is supposed to be PURPLE. Because of the following:It turns red when placed in acidic solutionIt turns blue when placed in alkaline solutionAnd purple when placed in neutral.
What if the blue litmus paper remains blue?
If the red litmus paper stays red, then the object tested may be either an acid or a neutral substance. The substance must be tested on blue litmus paper. if the blue paper stays blue, then it is neutral. If it turns red, then it is an acid.

What color does litmus paper turn when it is nuetral?
In a neutral solution litmus has a purple color.
What colour does blue litmus paper turn when dipped in alkaline?
Blue litmus paper stays blue in a neutral solution. It turns red only when in an acidic solution. Similarly, red litmus paper would stay red in a neutral solution and turn blue in an alkaline solution. Added: acidic: pH below 5.5 it turns (stays) red alkaline: pH above 8.0 it turns (stays) blue neutral, in between 5.5 and 8.0: its color is purple, between 'red and blue' or 'blue and red' A much better indicator paper is universal indicator paper. It is yellow and can tell you the exact pH of the solution it is dipped in, going yellow to red in acidic conditions, blue to purple in alkaline conditions and green in neutral conditions. The exact colour depends on the pH.
What color does acids turn red litmus paper?

When neutral litmus solution is added to alkaline solution?
When neutral litmus solution is added to an alkaline solution, the litmus solution will turn blue. This change in color indicates that the solution is basic or alkaline in nature. Litmus paper is commonly used as an indicator to determine the acidity or alkalinity of a solution.
What if the blue litmus paper remains blue?
If the red litmus paper stays red, then the object tested may be either an acid or a neutral substance. The substance must be tested on blue litmus paper. if the blue paper stays blue, then it is neutral. If it turns red, then it is an acid.
What do you have to add to litmus to make it purple?
Bases and alkali's turn litmus paper purple.
Why does blue litmus paper turn purple?
Blue litmus paper turns purple when exposed to a basic solution with a pH greater than 7. This color change occurs because the dye in the litmus paper reacts with the hydroxide ions present in the base, causing the paper to change from blue to purple.
If you are given Acidic basic and neutral solutions in three test tubes and you are given a strip of red litmus how will you identify the tree solutions?
To identify the three solutions using the red litmus strip, first, dip the strip into each solution one at a time. In an acidic solution, the red litmus will remain red, while in a basic solution, it will turn blue. In a neutral solution, the red litmus will also remain red. This simple test will help you classify the solutions as acidic, basic, or neutral.
What color does sodium fluoride turn litmus paper?
red turns red, blue turns blue, because it's neutral
