It turn purple-blue.
Red litmus paper remains red when a neutral solution is added. This is because neutral solutions do not affect the color of red litmus paper.
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.
When litmus is added to a solution of borax, it will turn blue. This indicates that the solution is basic or alkaline in nature. Borax, also known as sodium borate, is a weak base that can increase the pH of a solution.
When an acid is added to a base or alkaline solution, a neutralization reaction occurs. This reaction results in the formation of water and a salt. The pH of the solution typically moves closer to neutral (pH 7).
When toothpaste and an alkali are added to litmus paper, the litmus paper will turn blue. Litmus paper turns blue in the presence of bases and alkaline substances due to a shift in the pH level towards the alkaline range.
Red litmus paper remains red when a neutral solution is added. This is because neutral solutions do not affect the color of red litmus paper.
Sodium sulfate solution is neutral; the red litmus is purple.
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.

When litmus is added to a solution of borax, it will turn blue. This indicates that the solution is basic or alkaline in nature. Borax, also known as sodium borate, is a weak base that can increase the pH of a solution.
Litmus solution is a mixture of dyes dissolved in water.
When litmus is added to a solution of borax, the litmus paper may turn blue due to the alkaline nature of borax. Borax is a weak base that can cause litmus paper to change its color from red to blue.
When an acid is added to a base or alkaline solution, a neutralization reaction occurs. This reaction results in the formation of water and a salt. The pH of the solution typically moves closer to neutral (pH 7).
When toothpaste and an alkali are added to litmus paper, the litmus paper will turn blue. Litmus paper turns blue in the presence of bases and alkaline substances due to a shift in the pH level towards the alkaline range.
When red litmus paper is added to soap solution, it will turn blue. This indicates that the soap solution is alkaline in nature, as alkaline substances turn red litmus blue. This is because soap solutions typically have a pH above 7.
Blue litmus turns red in acid. Sodium carbonate solution is alkaline (basic), so nothing will happen when blue litmus is put into this. Red litmus will turn blue if added to sodium carbonate.
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.
If too little acid is added to an alkali, the resulting solution may not reach the desired neutral pH level. This could lead to the solution remaining basic or alkaline.
