What is a substance that changes color when an acid or a base is added?
An example of a substance that changes color when an acid or a base is added is litmus paper. Litmus paper turns red in acidic solutions and blue in basic solutions, making it a useful tool for identifying the pH of a substance.
What is the correct scientific term for a substance that changes colour in this way for litmus?
indicator
What does an acid do to blue litmus?
If a substance changes the color of a blue litmus paper to red, it is acidic blue to red
What is a compound that changes color when in contact with an acid or a base called?
That compound is called an acid-base indicator. These indicators change color based on the pH of the solution they are in, making them useful for identifying whether a substance is acidic or basic.
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.
Why no change in red litmus when placed in hydrochloric acid?
It is because the red litmus paper only changes its color (from red to blue) when exposed to any basic substance. Hydrochloric acid is acidic, thus there is no change in the color of the red litmus paper, although the acid would change the color of the blue litmus paper (pH paper that tests for acidity; changes from blue to red in the presence of acid)

What is the name given to a dye that changes colour depending on whether it's an acid or alkaline?
A dye that changes color depending on whether it's exposed to an acid or alkaline solution is called a pH indicator. pH indicators are commonly used in chemistry labs to determine the acidity or alkalinity of a solution based on the color change they undergo.
