Staying red, because of the acidic properties of Orange Juice (pH < 4)
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).
Oh, dude, when that litmus strip hits the tomato juice and goes all orange, it's like screaming at you, "Hey, this juice is acidic!" So yeah, technically speaking, that tomato juice is acidic. But hey, who needs litmus strips when you can just taste it and be like, "Yep, that's some tangy tomato juice right there."
It usually takes approximately 4 drops.
You can make a PH indicator solution out of blueberry juice, or you can buy litmus paper or use an indicator solution that you can buy at the store.
The color remain red because vinegar is an acidic solution.
When an indicator mixes with calamansi, it usually turns a pink or reddish color. This color change is due to the change in pH level caused by the acidic nature of calamansi juice.
Apple juice is slightly acidic and therefore red litmus will not change color.
When calamansi is mixed with eggplant, the color indicator will likely be a change in the eggplant's color. Calamansi juice is acidic and may cause the eggplant to slightly change in color, possibly becoming darker or more vibrant. This change can be useful for monitoring when cooking or preparing dishes that involve both calamansi and eggplant.
Blue litmus paper would turn red in orange juice.
Apple juice is a type of citric acid so it would turn blue litmus paper redish.
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.
As orange juice being an acidic solution, it turns blue litmus into red.
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.
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.
Orange juice is acidic because it tastes sour and turns litmus paper red. The acidity is due to the presence of citric acid in the juice, which imparts the sour taste and causes the litmus paper to change color.

Blue litmus paper turns red when grape juice is added, indicating that the solution is acidic.
