Lemon juice is an acid therefore, it turns blue litmus paper red and red litmus paper remains red
The litmus papers are used for checking the acidic and basic nature of any substance. That's why drop of lemon juice, which is by nature acidic, turns blue litmus into red(as the property of acidic solution is to change the color of blue litmus to red). So soap solution which is by nature basic will turn red litmus into blue (as the property of basic solution is to change the color of red litmus to blue).
Litmus turns pink in acid solutions like citric acid...blue in basic solutions.
"Soap" is a little vague, but most soaps are somewhat alkaline and if I were forced to bet on what would happen I would guess that the litmus would turn blue again. However, depending on the kind of soap, it might do nothing except get it wet and soapy.
As soap is alkaline in nature, it turns red litmus paper blue

Lemon juice is an acid and blue litmus paper turns red when dipped in an acidic liquid.
Lemon juice contains citric acid so blue litmus paper dipped in lemon juice will turn red indicating that it is acidic.
Red because the lemon juice is acidic.
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).
blue
because it is an acid.
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.
