How are pH indicators classified?
pH indicators are classified based on the pH range over which they change color. They can be classified as either acidic, basic, or universal indicators. Acidic indicators change color in acidic solutions, basic indicators change color in basic solutions, and universal indicators change color over a wide pH range.
Are indicators acidic or basic in nature?
Indicators can be both acidic and basic in nature, depending on their color change properties in response to different pH levels. Some indicators change color in acidic solutions, while others change color in basic solutions.
Are indicators acidic?
Indicators are substances that change color in response to changes in pH, indicating whether a solution is acidic, basic, or neutral. Some indicators change color in acidic environments, while others change color in basic environments. The specific indicator used will determine how it responds to acidity.
What are acid-base indicators?
Acid-base indicators, are chemicals that change color in response to acidic or basic conditions.
How many types of indicators are there?
There are two types. Those are acidic or basic.
What colour does battery acid go in universal indicators?
Battery acid typically turns red in universal indicators, indicating that it is acidic.
What are the names of the indicators that tell us if something was acid or alkaline?
The indicators that tell us if a substance is acidic or alkaline include litmus paper, pH paper, universal indicator solution, and phenolphthalein. These indicators change color based on the pH of the substance they are in contact with, helping to determine if it is acidic or alkaline.
Do acids effect indicators?
Yes, acids can affect indicators by changing their color. Indicators are substances that change color in response to the acidic or basic nature of a solution. Acids can cause indicators to change color depending on their pH level.
What indicators used in redox titration?
Some common indicators used in redox titrations are potassium permanganate (KMnO4), which changes color from purple to colorless in acidic conditions, and potassium dichromate (K2Cr2O7), which changes from orange to green in acidic conditions. Other indicators include starch-iodine complex and ferroin.
What happens when acids come in contact with each indicators?
The color of indicators is changed in acidic solutions.For example thymol blue is red at low pH.
What is the smell of acid in olfactory indicators?
The smell of acid in olfactory indicators is often described as sour, sharp, pungent, or acidic. It can be perceived as a strong and unpleasant odor.
What are the different indicators used in the laboratory?
to test if a solution is acidic, alkaline or basic
