What else can I help you with?
What is the color of phenolpthalein in?
Phenolphthalein is colorless in acidic solutions and pink in basic solutions.
What color would tap water turn with phenolphthalein?
Generally tap water is acidic. There is no color changes.
Why we use phenopthline as indicator for determining theconcentration of oh?
Phenolphthalein change the color from pink in basic solutions to colorless in acidic solutions.
What color does phenolphthalein turn in base?
if concentration is particularly strong then it became purple
What is the colour of phenolphthalein after addition of dilute HCl?
The color of phenolphthalein after the addition of dilute HCl is colorless. Phenolphthalein is typically pink in basic solutions but turns colorless in acidic conditions due to the change in pH.
How will Phenolphthalein help you test for unknown substances?
Phenolphthalein is a pH indicator that changes color in response to different pH levels. By using phenolphthalein, you can determine if a solution is acidic or basic based on the color change it exhibits. This can help you identify unknown substances by comparing the color change with known pH values of different substances.
Phenolphthalein change color when mixed with hydrochloric acid?
Phenolphthalein is a pH indicator that changes color in response to a change in pH. When mixed with hydrochloric acid (a strong acid), phenolphthalein will turn colorless due to the decrease in pH, indicating an acidic solution.
What happens if phenolphthalein was added to salts?
If phenolphthalein is added to a solution of salts, it will not undergo any specific reaction. Phenolphthalein is used as an indicator in acid-base titrations, where it changes color depending on the pH of the solution. Since salts do not have acidic or basic properties, phenolphthalein will not exhibit any color change.
Do bases turn phenolphthalein clear?
No, bases turn phenolphthalein pink or purple in color. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions with a pH higher than around 8.2.
What is indicator which has no color with the acidic medium?
Phenolphthalein and other indicators which themselves are weak acid show a colour change in basic medium (between pH value 7.1 to 14) so in acids they remain unchanged.
Which indicator gives us reddish pink color in acidic solution?
The red or pink color in an acidic solution is typically due to the presence of an acid-base indicator called phenolphthalein. In acidic conditions, phenolphthalein turns colorless, while in basic conditions it turns red or pink.
Why testing with phenolphthalein would not show weather the solution is acidic or neutral?
Phenolphthalein changes color at a pH around 8.2 to 10, indicating alkalinity. Since it does not change color in acidic or neutral solutions, it is not suitable for distinguishing between acidic and neutral solutions. Other indicators like litmus paper would be more appropriate for that purpose.
