8) This is an indicator that is colorless in a neutral of acid solution but turns magenta (bright pink) in a base?
The indicator you are describing is phenolphthalein. In neutral or acidic solutions, phenolphthalein remains colorless, but when the pH exceeds approximately 8.2, it changes to a vibrant magenta, indicating a basic environment. This property makes it useful in titrations and various chemical analyses to visually signal pH changes.
What else can I help you with?
What color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.
What color does phenolphthalein turn when dipped in water?
Phenolphthalein is colorless when in contact with water or any neutral solution. It only turns pink or magenta in the presence of basic solutions with a pH greater than 8.2.
What is the colour of universal indicator solution in a neutral solution?
The Universal Indicator would go green which is pH 7.
What does the change in color of dropping phenolphthalein indicator?
Phenolphthalein is a pH indicator that changes color based on the acidity or alkalinity of a solution. In acidic conditions (pH below 8.2), it is colorless, while in neutral to slightly basic conditions (pH 8.2 to 10), it turns pink. Therefore, when phenolphthalein is added to a solution and the pH changes, the indicator will either remain colorless or change to pink, indicating the pH level of the solution. This property makes it useful in titrations and other chemical analyses to determine the acidity or basicity of a solution.
Which indicator could be used to identify a neutral solution?
A neutral solution will have a pH of 7. One indicator that can be used to identify a neutral solution is litmus paper, which will remain its original color (usually blue or red) when immersed in a neutral solution.
What indicator has no color at all?
phenolphthalien when added to an acidic solution has a colourless indicator. but shows pink colour for basic solution.
What color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.
What color does phenolphthalein turn when dipped in water?
Phenolphthalein is colorless when in contact with water or any neutral solution. It only turns pink or magenta in the presence of basic solutions with a pH greater than 8.2.
What colour should sodium sulphate be in universal indicator?
Sodium sulfate is typically colorless in universal indicator. Universal indicator is a pH indicator that changes color based on the pH of a solution, and sodium sulfate is a neutral compound that does not significantly affect the pH.
What colour will a neutral solution become if a universal indicator was added?
A neutral solution added to universal indicator will turn green.
What is the colour of phenolphthalein above pH equals 9?
Phenolphthalein is the PH indicator used to detect the acidity of the solution. When the solution is acidic or near-neutral (PH<8.2), it's colorless; when the solution is basic (8.2<PH<10.0),it will turn from colorless to pink, and gradually turns fuchsia when PH reaches 12.0, back to colorless when overpasses 12.0.
What is the colour of universal indicator solution in a neutral solution?
The Universal Indicator would go green which is pH 7.
Which indicator could be used to identify a neutral solution?
A neutral solution will have a pH of 7. One indicator that can be used to identify a neutral solution is litmus paper, which will remain its original color (usually blue or red) when immersed in a neutral solution.

What is the color of phenolphthalein indicator in acidic medium?
it goes colourless in an alkiline soloution but in an acidic substance it goes a fushia pink colour! You are WRONG! The solution will be colourless at acidic and neutral pH and goes pink above about pH 8, I hope you aren't a science teacher.
What Color will turn a solution of washing soda and lemon juice when its neutralized?
When a solution of washing soda (sodium carbonate) and lemon juice (which contains citric acid) is neutralized, the resulting solution typically turns from a basic (alkaline) state to neutral, which may not produce a distinct color change. However, if a pH indicator like phenolphthalein is used, the solution will shift from pink (indicating basicity) to colorless as it approaches neutral pH. If using universal pH indicator, the color may change to green, indicating a neutral pH around 7.
What will salt solution turn into with universal indicator?
A salt solution with universal indicator will likely show a neutral pH, appearing green in color. This is because salts are typically pH-neutral compounds that do not significantly affect the acidity or alkalinity of a solution when dissolved in water.
