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 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.
Universal indicator is a solution that changes what in an acidic or alkali solution?
Universal indicator doesn't change anything in an acidic or alkali solution. All universal indicator does is show how acidic or alkaline a solution is (red being acidic, green being neutral and blue being alkali)
What is the color of the indicator when it mixes to calamansi?
When an indicator mixes with calamansi, it usually turns a pink or reddish color. This color change is due to the change in pH level caused by the acidic nature of calamansi juice.

How does turmeric work as natural indicator?
Turmeric contains a compound called curcumin which gives it a vibrant yellow color. In acidic solutions, curcumin changes to a reddish color, while in basic solutions, it changes to a dark brown color. This color change makes turmeric a useful natural indicator for determining the acidity or basicity of a solution.
What is the colour change of carrot indicator in acid medium?
Carrot indicator turns yellow in an acidic medium. This change in color is due to the presence of anthocyanins that react with the acidic solution.
Why does the universal indicator change colour it had put vinegar?
Universal indicator changes color when exposed to vinegar due to the change in pH. Vinegar is acidic, which causes the indicator to shift to a color that corresponds to that level of acidity.
What color when acid is put on china rose indicator?
When acid is put on china rose indicator, the indicator will turn red in color. This color change indicates that the solution is acidic. China rose indicator contains anthocyanin pigments that change color based on the pH of the 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 substance will make universal indicator turn orange?
An acidic substance will turn universal indicator orange. This occurs because universal indicator contains a mixture of dyes that change color based on the pH of the solution. In an acidic environment, the indicator will shift towards the orange end of the color spectrum.
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.
