Chemical Indicator Definition ~ 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. This could be a color change precipitate formation bubble formation temperature change or other measurable quality. These are called acid base indicators. Indicators are substances whose solutions change color due to changes in ph. Chemical indicators cis as defined by the association for the advancement of medical instrumentation aami and international organization for standardization iso are devices used to monitor the presence or attainment of one or more of the parameters required for a satisfactory sterilization process or used in a specific test of sterilization equipment. An example is that the substance called methyl yellow which imparts a yellow color to an alkaline solution. A chemical indicator is used to slow down the chemical reaction by changing its color until the reaction either finished or reached its equilibrium point. Steris s complete portfolio of chemical indicators includes both internal and external indicators. The chemical indicator is a substance that provides a clear sign or indication by a color change of the presence or absence of a threshold concentration of a chemical species such as an acid or base in a solution. Chemical indicators use one or more chemicals that undergo either a physical or chemical change that is visible to the human eye after exposure to predetermined critical parameters like temperature time or sterilant. Indeed lately has been sought by users around us, maybe one of you personally. People now are accustomed to using the internet in gadgets to view video and image information for inspiration, and according to the title of the article I will discuss about Chemical Indicator Definition.

A chemical indicator is used to slow down the chemical reaction by changing its color until the reaction either finished or reached its equilibrium point. These are called acid base indicators. Indicators are substances whose solutions change color due to changes in ph. A chemical indicator is a substance that undergoes a distinct observable change when conditions in its solution change. This could be a color change precipitate formation bubble formation temperature change or other measurable quality.

They are usually weak acids or bases but their conjugate base or acid forms have different colors due to differences in their absorption spectra.
