What is the colour of universal indicator solution in a neutral solution?
The color of universal indicator solution in a neutral solution is green.
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.
Why sugar solution stays yellow in a turmeric indicator?
Turmeric contains a compound called curcumin which changes color from yellow to red in acidic solutions. When added to a sugar solution, which is neutral, the turmeric indicator remains yellow because the pH of the solution is not acidic enough to induce the color change in curcumin.
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.
What would you use to show when an acid has completely reacted with an alkali?
You can use a pH indicator to show when an acid has completely reacted with an alkali. The pH indicator changes color when the solution reaches a neutral pH, indicating that the reaction is complete.
What is the colour of universal indicator solution in a neutral solution?
The color of universal indicator solution in a neutral solution is green.
What indicator has no color at all?
The indicator that has no color at all is a colorless indicator, such as phenolphthalein in its neutral pH state.
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 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 colour would universal indicator show in an aqueous solution of sugar and why?
The universal indicator would likely show a green color in an aqueous solution of sugar. This is because sugar is a neutral compound and does not significantly affect the pH of the solution, resulting in a green color indicating a neutral pH.
Why sugar solution stays yellow in a turmeric indicator?
Turmeric contains a compound called curcumin which changes color from yellow to red in acidic solutions. When added to a sugar solution, which is neutral, the turmeric indicator remains yellow because the pH of the solution is not acidic enough to induce the color change in curcumin.
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.
What changes color on pH?
An indicator is a substance that changes color based on the pH of a solution. It shifts its color based on whether the solution is acidic, neutral, or basic. Examples of indicators include litmus, phenolphthalein, and bromothymol blue.
Can sugar turn universal indicator red?
Yes, sugar is a neutral substance and will not change the color of universal indicator. Universal indicator changes color in response to changes in pH, indicating the acidity or alkalinity of a solution. Sugar does not alter the pH of a solution significantly.
The color of methylorange indicator in a neutral solution?
an universal indicator paper tells you how acid or how alkali it is acid - red alkali - blue neutral - green
What colour universal indicator turns to a neutral?
Green is the color that universal indicator turns to when it is neutral.
What would you use to show when an acid has completely reacted with an alkali?
You can use a pH indicator to show when an acid has completely reacted with an alkali. The pH indicator changes color when the solution reaches a neutral pH, indicating that the reaction is complete.
