Which of the unknown colorless solutions is (are) acidic
Phenolphthalein is colorless in acidic solutions and pink in basic solutions.
In acid conditions it is colorless and in basic conditions it is pink and then bright red
No, phenolphthalein is colorless in acidic solutions. It turns pink or red in basic solutions.

Phenolphthalein, a pH indicator, is colorless in acidic solutions and turns pink in basic solutions due to a change in its molecular structure. In an acid, the phenolphthalein molecule retains its colorless form as it undergoes a chemical reaction with the acidic environment.

Phenolphthalein change the color from pink in basic solutions to colorless in acidic solutions.
No, phenolphthalein is colorless in acidic solutions. It turns pink or red in basic solutions.

It is an acid - base indicator. Often used in titrations, it turns colorless in acidic solutions and pink in basic solutions.. litmus paper color... Red in acidic solution n blue in alkaline solution
Litmus paper reacts with acidic solutions by turning red and with basic solutions by turning blue. Phenolphthalein changes color from colorless in acidic solutions to pink in basic solutions. Universal indicator changes color according to the pH of the solution, exhibiting a range of colors from red for acidic solutions to purple for basic solutions.
No, phenolphthalein turns colourless when it comes into contact with an acid. It only turns magenta with a base (alkali)
Very strong acid solutions that have phenolphthalein added to them turn orange, but in general acidic solutions with phenolphthalein are colorless. If the solution is titrated to slightly basic (pH > 8.2) it will turn pink. Note that in extremely basic solutions (pH > 13) it will revert to colorless again.
Some common indicators for acids include litmus paper (blue to red for acidic solutions), phenolphthalein (colorless to pink/red for acidic solutions), and methyl orange (red to yellow for acidic solutions). For alkalis, indicators include litmus paper (red to blue for basic solutions), phenolphthalein (colorless to pink/red for basic solutions), and methyl orange (yellow to red for basic solutions).
Phenolphthalein is colorless in acidic solutions and pink in basic solutions. By adding phenolphthalein to a substance, you can observe the color change to determine if the substance is acidic or basic based on the change in color.
