What is a substance that changes color?
An example of a substance that changes color is litmus paper. Litmus paper is commonly used in chemistry as an indicator to determine the acidity or alkalinity of a solution, as it changes color in response to the pH level of the substance it is in contact with.
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.
A substance such as litmus that signals the presence of something?
An indicator is a substance that changes color in response to the presence of specific substances in a solution. Litmus is a common indicator that changes from blue to red in the presence of an acid and from red to blue in the presence of a base. This color change helps to identify the nature of the solution being tested.
What substance changes color when exposed to an acid or base?
An indicator is a substance that changes color when exposed to an acid or base.
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.

What do you call a substance which is used to show changes in pH by its change in color?
An indicator. It is a substance that changes color in response to a change in pH, making it a useful tool in chemistry to visually determine the acidity or basicity of a solution.
Substance that is of one color in an acid solution and of another color in a basic solution is a what?
A substance that changes color depending on the pH of the solution is known as an acid-base indicator. These indicators are often used in chemistry to visually determine the acidity or basicity of a solution based on the color change they exhibit.

What happens after dipping a substance into a pH solution?
When a substance is dipped into a pH solution, it will either change color due to a chemical reaction with the solution, or it may not show any visible change if the substance is neutral. This process helps determine the acidity or basicity of the substance based on the pH solution's color change.
What is a substance that is used to determine an acid or a base?
An indicator is a substance that changes color in response to the acidity or basicity of a solution. Common examples include litmus paper, phenolphthalein, and bromothymol blue.
What type of nutrient can be detected using iodine solution?
Iodine solution is commonly used to detect the presence of starch. When iodine solution comes into contact with starch, it changes color from brownish-yellow to a blue-black color. This color change is a positive indication of the presence of starch in a substance.
What is a natural acid/base indicator and how does it function in determining the pH of a solution?
A natural acid/base indicator is a substance that changes color in response to the acidity or alkalinity of a solution. It functions by undergoing a color change based on the pH level of the solution it is placed in. This color change can help determine the pH of the solution, with different colors indicating different pH levels.
What does iodine solution indicate?
Iodine solution is commonly used as an indicator in starch tests. When iodine solution is added to a substance, such as food or a biological sample, it turns blue-black in the presence of starch. This color change indicates the presence of starch in the sample.
