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.
How can you differentiate strong acid from a weak acid using an indicator?
You can differentiate between a strong acid and a weak acid using an indicator by examining the pH change. A strong acid will cause a more significant decrease in pH and produce a more intense color change in the indicator compared to a weak acid, which will cause a less dramatic change in pH and produce a less intense color change.
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.

What indicator's could be used to produce a color change at both PH 2 and PH?
thymol blue,cresol red,and universal indicatior
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.

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.
How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
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.
Why titration not require an external indicator?
Titration does not always require an external indicator because some reactions involved in titration produce a noticeable color change, known as a self-indicating reaction. This color change signals the endpoint of the titration without the need for an external indicator. Examples include the reaction between acid and base or with certain metal ions.
