because it is an acid.
Lemon juice is an acid therefore, it turns blue litmus paper red and red litmus paper remains red
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.
Dipping blue litmus paper in lemon juice is a chemical change. The acidic nature of lemon juice causes a chemical reaction with the blue litmus paper, turning it red. This change in color indicates a chemical transformation of the litmus paper due to the interaction with the acid in the lemon juice.
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.
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).
As Lemon Juice is an Acid, the colour of the Red Litmus Paper will stay the same.
blue
whenever a litmus paper turns blue to red it means the solution is acidic this definitely means apple juice is acidic
Lemon juice is acidic due to its high citric acid content, which has a pH below 7. Blue litmus paper is used to test for acidity; when it comes into contact with an acid, it changes color to red. Therefore, when lemon juice is applied to blue litmus paper, it turns red, indicating the presence of acid.
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
A household product that will turn litmus paper red is an acidic substance, such as vinegar or lemon juice. Acids have a pH below 7, which is the range that litmus paper turns red in.
