A substance that is used to determine an acid or base is called?
An indicator is a substance that is used to determine whether a solution is acidic or basic by changing color based on the pH of the solution. Examples of indicators include litmus paper, phenolphthalein, and bromothymol blue.
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.
Which substance turns the universal indicator green?
A substance that turns universal indicator green is a base. Bases have pH levels higher than 7, which causes the universal indicator to turn green.
What is iodine used as an indicator for?
