What else can I help you with?
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 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.
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 would you use to show when an acid has completely reacted with an alkali?
A pH indicator: the color is changed at the end of the reaction, when the solution become alkaline.
What is the colour of universal indicator solution in a neutral solution?
The Universal Indicator would go green which is pH 7.
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).
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.
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.
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 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?
A pH indicator: the color is changed at the end of the reaction, when the solution become alkaline.
