What color does base turn a universal indicator?
The color of a universal indicator in a basic solution is usually purple or blue.
Compounds that react with acidic or basic solutions to produce certain colors?
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.
What colour does the universal indicator turn when mixed with coffee?
Universal indicator typically turns a reddish-brown or yellowish-brown color in acidic solutions like coffee.
When you mix sugar and a universal indicator what colour does it become?
When sugar is mixed with universal indicator, it typically does not change color as the indicator is primarily used to measure pH levels in solutions, not sugar content. The indicator will only change color based on the acidity or alkalinity of the solution it is in.
How is the pH of a solution is measured using universal indicator?
The pH of a solution is measured using universal indicator by adding a few drops of the indicator to the solution and observing the color change. The color of the solution corresponds to the pH level on the universal indicator color scale, which ranges from red (acidic) to purple (neutral) to blue (basic).
Which liquid or liquids caused the universal indicator to change colour?
The universal indicator changes color in response to the acidic or basic nature of a solution. Acidic solutions will turn the indicator to a red color, while basic solutions will turn it to a blue or purple color. Different liquids with varying pH levels can cause the universal indicator to change color accordingly.
What color does base turn a universal indicator?
The color of a universal indicator in a basic solution is usually purple or blue.
What happens when you add universal indicator to water?
When universal indicator is added to water, it will change color based on the pH of the water. Universal indicator shows a range of colors corresponding to different pH levels, such as red for acidic solutions, green for neutral solutions, and blue/purple for basic solutions. This color change allows you to determine the approximate pH of the water.

How a mixture of methyl orange litmus and phenolphthalein could be used as a type of universal indicator?
A mixture of methyl orange, litmus, and phenolphthalein can be used as a universal indicator because each indicator covers a different pH range. Methyl orange turns red in acidic solutions, litmus turns red in acidic solutions and blue in basic solutions, and phenolphthalein turns pink in basic solutions. By observing the color change of the mixture, you can determine the approximate pH of the solution being tested.
Is litmus neutral?
Litmus is not neutral, but rather an indicator that changes color in the presence of acidic or basic solutions. It turns red in acidic solutions and blue in basic solutions.
What is universal indicator state the purpose for which this indicator is used?
Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.
Do basic solutions turn the dye litmus red?
No, basic solutions turn litmus dye blue. Litmus is a pH indicator that changes color in response to a solution's acidity or basicity.
What are the color of universal indicator in toothpaste?
Universal indicator typically changes color based on the pH level of a substance. In toothpaste, the color of universal indicator can vary depending on the specific formulation and ingredients used. The color may range from pink (indicating a slightly acidic pH) to blue or purple (indicating a slightly basic pH).
