How does an acid affect an indicator?
Acids typically change the color of an indicator by donating a hydrogen ion (H+) to the indicator molecule, altering its structure and causing a shift in color. The specific color change depends on the pH range of the indicator and its chemical properties.
What color does salt turn when mixed with liquid indicator?
When salt is mixed with a liquid indicator, it may not change color immediately. The liquid indicator's color change is usually due to a change in pH levels rather than the presence of salt. Salt does not typically cause a color change in liquid indicators.
What can be used as an indicator for a physical change and a chemical change?
Change in Color.
Which color does a base change when mixed with hibiscus indicator?
A base will change the color of hibiscus indicator from red to green or blue, depending on the strength of the base.
Why do indicators in chemistry change color when placed in different substances?
Indicators change color due to a chemical reaction between the indicator and the substance that alters the light absorption properties of the indicator molecule. This change in absorption properties results in a different color being observed. Different substances interact differently with the indicator molecule, leading to the color change.
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.
How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
What is the color of marigold flower indicator when acidic substance is added to it?
When an acidic substance is added to marigold flower indicator, the color generally turns red or pink. This color change indicates the presence of acidity in the substance being tested.
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.
What color change does starch indicator solution make in the absence of starch?
Starch indicator solution will remain its original color (usually colorless) in the absence of starch. Without starch present, there will be no color change observed when using starch indicator solution.
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 will lemonade turn into when red cabbage indicator is in it and why?
Lemonade will turn pink when red cabbage indicator is added to it. This color change is due to the red cabbage indicator being sensitive to pH levels. The acidity of the lemonade will cause the red cabbage indicator to change color to pink.
