wel, i hav performed this experiment and actually used blue and pink litmus papers. blue litmus turned pink and pink remained pink when subjected to vapors emerging from the mouth of the test tube being heated.
i hope this helps...
The colors of litmus is different; this depends on the pH.
When acids and alkalis are mixed, the pH of the solution changes. Indicators such as litmus paper will change color based on the new pH. Acids turn blue litmus paper red, while alkalis turn red litmus paper blue.
Methanol is a neutral substance and typically does not change the color of litmus paper. Litmus paper changes color in the presence of acidic or alkaline substances.
Acid turns litmus paper red.
Litmus paper turns blue in a base.
THE COLOUR of the litmus paper will not change as a salt solution is neutral

The color of litmus paper in acidic solutions is red.

Blue litmus paper
Purple litmus paper will remain purple when dipped in tap water. Tap water is typically neutral or slightly basic, so it will not cause a color change in purple litmus paper.
Alcohol does not significantly affect litmus paper. Litmus paper is primarily used to test for acidity or alkalinity in solutions by changing color, and alcohol does not typically cause a noticeable color change on litmus paper.
In a neutral solution litmus has a purple color.
the red litmus paper turns to blue
