Question

what happens if we put red litmus paper in lemon water​

Answer 1

Answer:

Litmus being a natural dye and indicator turns the color to red/ blue. When drops of lemon juice are put on blue litmus it turns red because of presence of acids. Now, when we will put some drops of soap solution on the same position i.e. on red litmus paper then the color of the litmus will change to blue.
