Blue litmus paper turns red when Grape Juice is added, indicating that the solution is acidic.
The five natural indicators are litmus, red cabbage juice, turmeric, grape juice, and beetroot juice. These indicators change color in the presence of acids or bases, making them useful for determining the pH of a solution.
As orange juice being an acidic solution, it turns blue litmus into red.
Litmus paper will turn red in acidic solutions, such as orange juice, indicating its acidity.
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.
it turns acidic or very basic
Grape juice typically has a pH ranging from 3 to 4, which is acidic. When tested with litmus paper, it would turn blue litmus paper red, indicating its acidic nature. Red litmus paper would remain red, as it does not change color in acidic solutions.
Because the pH of the juice is changed.
Gold grape juice is orange.
Apple juice is slightly acidic and therefore red litmus will not change color.
The color change in grape juice when an acid or base is added is due to the presence of anthocyanins, which are pigments found in the juice. These pigments can change their structure depending on the pH of the solution; in acidic conditions, they often appear red, while in basic conditions, they can turn blue or green. This reaction highlights the sensitivity of anthocyanins to pH changes, making grape juice a useful natural pH indicator.
Litmus paper would turn red if apricot juice, which is acidic, was dropped on it. This is because litmus paper turns red in the presence of an acid.

Blue litmus paper would turn red in orange juice.

Red, due to the citric acid.
Apple juice is a type of citric acid so it would turn blue litmus paper redish.
Potato juice is typically neutral or slightly acidic, so if you test it with litmus paper, blue litmus paper will remain blue, and red litmus paper will remain red. This indicates that potato juice does not change the color of either type of litmus paper, reflecting its neutral pH.
