An indicator is used to determine the pH of a solution by changing color at specific pH levels. It provides a visual signal of whether the solution is acidic, neutral, or basic based on the color change it undergoes. Indicators are often added to solutions during titration experiments to help determine the endpoint of a reaction.
What else can I help you with?
Do Acids turn universal indicator solution yellow or red?
Acids turn universal indicator solution red.
What colour does the univeral indicator turn in ammonia solution?
It depends on the concentration of the ammonia solution as the universal indicator can show a huge variety of colors.
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.
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).
What colour will a neutral solution become if a universal indicator was added?
A neutral solution added to universal indicator will turn green.
What color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.

Benedict solution is the chemical indicator for simple sugars.
What is the colour of universal indicator solution in a neutral solution?
The Universal Indicator would go green which is pH 7.

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).
What colour will a neutral solution become if a universal indicator was added?
A neutral solution added to universal indicator will turn green.
When using an indicator is a chemical reaction occurring?
Yes, the indicator react with the solution.
Why doesn't sugar solution change the colour of a green universal indicator what does it tell us about the sugar solution?
Sugar solution does not change the color of a green universal indicator because it is neutral, neither acidic nor basic. This tells us that the sugar solution is pH neutral, meaning it has a pH level around 7 and is not acidic or alkaline.
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.
