Acid or alkalis I think. I don't realy know for sure but I think you put litmus paper in acid or alkali. I dunno, I just remember this science lesson once and we were doing about this sorta thing...not sure-to be honest I'm just putting awnsers to these questions 'cos I'm bored. :P lol
Since the PH value of the lemon juice is around 2.3 (acidic), the litmus paper would turn red.
pH
whenever a litmus paper turns blue to red it means the solution is acidic this definitely means apple juice is acidic
It would remain red, red litmus paper only reacts to blue in the presence of a base. Lemon juice is acidic and thus wouldn't turn the paper a color. If blue litmus paper was used in the lemon juice it would turn red. Consequently dipping blue litmus paper in a base won't change the color because it does not react with bases, only acids.
light pink
white
The litmus paper will turn red.
Lemon juice contains citric acid so blue litmus paper dipped in lemon juice will turn red indicating that it is acidic.
Lemon juice is an acid and blue litmus paper turns red when dipped in an acidic liquid.
blue
Lemon juice contains citric acid so blue litmus paper dipped in lemon juice will turn red indicating that it is acidic.Blue litmus paper become red in acidic solutions (lemon juice contain citric acid).

Lemon juice is an acid therefore, it turns blue litmus paper red and red litmus paper remains red

Litmus is a dye extracted from lichens, a plant. Upon addition of acid, litmus turns red whilst on addition of base, litmus turns blue. Being acidic, containing citric acid, lemon juice is expected to turn violet litmus paper red.
As Lemon Juice is an Acid, the colour of the Red Litmus Paper will stay the same.
