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.
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 is the term for a substance that changes color according to the pH of the solution?
The term for a substance that changes color according to the pH of the solution is an indicator. Indicators are commonly used in chemistry to visually determine the acidity or basicity of a solution based on color changes.
What property is a characteristic of a pure substance that can be observed without changing the substance into something else?
The property you are referring to is known as an intensive property. Intensive properties are characteristics of a substance that do not depend on the amount of the substance present, such as density, color, temperature, and boiling point. These properties can be used to identify and classify substances without altering their chemical composition.

What is the difference between a phisical change and a chemical change?
A physical change is one you can see. It changes the size, shape, or color of something. A chemical change is one that changes the composition of something. Basically, when a substance is changed into a different substance.

What pyshical property helps identify a substance?
color,odor,texture,and shape.
What is it called when a substance changes color in response to pH?
This is a pH indicator.
How can physical properties be used to identify substance?
Every substance has certain properties that show things about them, such as odor, taste, malleability, hardness, color, state at room temperature, and melting/boiling point. If you know the color of a substance, it is far easier to determine what that substance is, and if you know the color and the boiling point, your choices are limited even further. Using the physical properties of a substance, you can identify the substance based off of its unique properties or combinations of properties.
Would you expect a pure substance to be the same color throughout?
no we cannot everything changes with time even a pure substance looses it's some of the properties after some time so the color also changes .
