What is the chemical used to identify changes in pH?
The chemical commonly used to identify changes in pH is an indicator, such as litmus paper or phenolphthalein. These indicators change color in response to changes in the acidity or alkalinity of a solution, allowing for easy visual detection of pH changes.
Why do you need indicators of chemical change?
Indicators of chemical change are needed to detect when a chemical reaction has occurred. They can provide visual cues, such as color changes or gas production, that indicate a chemical transformation has taken place. These indicators help scientists and chemists monitor and understand the progress of reactions.
What can indicators identify?
Indicators are used frequently for testing pH; but many other indicators exist for other compounds or ions.
What is metallochromic indicators?
Metallochromic indicators are chemical compounds that change color when they bind to metal ions. They are commonly used in analytical chemistry to detect the presence of metal ions in a solution. The color change is due to the formation of a complex between the indicator and the metal ion.
What are the indicators that can be used to determine dissociation constant?
If you mean chemical indicators as used for indicating pH and reaction end-points, the answer is none, unless you are only looking for a very rough estimate at dissociation constant. The error involved in using an indicator would be very large. If you used an indicator, choice would depend on the compound, what its dissociation constant was and what it dissociated to.
What are chemical indicators?
Chemical indicators are substances that change color in response to a chemical change. They are often used to visually indicate the presence of a specific substance or the completion of a chemical reaction. They are commonly used in laboratory experiments to monitor chemical reactions or to determine the endpoint of a titration.

Do some plants and flowers give dyes that are used as indicators?
yes some really gave the raw material for indicating chemical presence.
True or false - is it possible to make indicators out of vegetables?
Yes, you can. They are not as good as the chemical indicators, but they can indicate a basic acid/alkali difference.
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.
What vegetables or fruits make good chemical indicators?
tomato's red cabbage
What chemical an you use to test acids and alkali's?
These substances are called pH indicators.
What can indicators identify?
Indicators are used frequently for testing pH; but many other indicators exist for other compounds or ions.
What substance is used as an acid-base indicator?
Phenolphthalein, Metyl Orange, Methyl Red, Thymol Blue and Bromothymol Blue are some of the commonly used acid-base indicators. The property of such indicators should be the capability of showing a distinct chemical change with respect to a particular pH value.
What is metallochromic indicators?
Metallochromic indicators are chemical compounds that change color when they bind to metal ions. They are commonly used in analytical chemistry to detect the presence of metal ions in a solution. The color change is due to the formation of a complex between the indicator and the metal ion.
How many types of indictors are used in titration?
There are two main types of indicators used in titration: color indicators and pH indicators. Color indicators change color at specific pH ranges to indicate the endpoint of the titration, while pH indicators change color based on the pH of the solution.
