What do all indicators have in common?
Whereas most dyes do not change color with the amount of acid or base present, there are many molecules, known as acid – base indicators , which do respond to a change in the hydrogen ion concentration.
Most of the indicators are themselves weak acids.
The most common indicator is found on “litmus” paper..
What is a Class 1 indicator?
Class 1: Indicators are meant for use with individual items, for example, containers or cans to indicate that a unit has been directly subjected to the sterilization test cycle and differentiate between processed and non-processed units.

What are the three types of indicator?
There are three types of economic indicators: leading, lagging and coincident.
What indicator means?
Indicators are substances whose solutions change color due to changes in pH. … They are usually weak acids or bases, but their conjugate base or acid forms have different colors due to differences in their absorption spectra.
What is the function of indicator?
The common application of indicators is the detection of end points of titrations. The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.
What are indicators explain with example?
Chemical indicator, any substance that gives a visible sign, usually by a colour change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. An example is the substance called methyl yellow, which imparts a yellow colour to an alkaline solution.
