What are the visual indicators?
A visual indicator is a “marker” that helps users quickly locate an item that has an important distinctive attribute within a list of otherwise similar objects. Indicators on ecommerce websites are often used to denote exclusive products or items on sale, as seen on the mobile screenshot above of REI.com.
Which is an example of a visual indicator?
Alcoholic solution of phenolphthalein (1%) has been frequently applied in titration as a pH visual indicator to reveal information about other compounds, including mineral acids, organic acids, and most alkalis.
Is onion a visual indicator?
Onion, clove and vanilla extract are olfactory indicators because they respond to acids and bases by change in odour.
What is visual titration in chemistry?
The action of indicators in visual complexometric titrations is based on changing a particular optical property (absorption, fluorescence etc.) of the solution titrated in the conditions where the concentration of the free metal aquo ion approaches a defined borderline concentration level.
