What are the advantages of natural indicators?
natural indicators are cheap, while universal indicators are hard to obtain.
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.
Why can't a single indicator be used to tell the pH of a solution?
A single indicator cannot be used to accurately determine the pH of a solution because indicators change color over a range of pH values rather than at a specific pH. Different indicators have varying color changes at different pH ranges, so using multiple indicators or pH meters provides a more precise measure of the pH of a solution.
What changes color on pH?
An indicator is a substance that changes color based on the pH of a solution. It shifts its color based on whether the solution is acidic, neutral, or basic. Examples of indicators include litmus, phenolphthalein, and bromothymol blue.
What are examples of self indicators in chemistry?
Examples of self indicators in chemistry include phenolphthalein, bromothymol blue, and litmus. These substances change color based on the pH of the solution they are in, making them useful for visually determining whether a solution is acidic or basic without needing to add any additional indicators.
Examples of plant indicators for measuring pH values?

What are the advantages of natural indicators?
natural indicators are cheap, while universal indicators are hard to obtain.
How indicators works?
pH indicators change their color according to the pH of a solution.
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.
What are indicators in acid-base reactions?
Indicators change color based on the pH of the solution. You want to pick an indicator with a similar pKa (acid-dissociation constant) as the pH at which the reaction becomes what you desire it to be. Examples include phenolphthalein, bromthymol blue, and phenol red.
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.
Why can't a single indicator be used to tell the pH of a solution?
A single indicator cannot be used to accurately determine the pH of a solution because indicators change color over a range of pH values rather than at a specific pH. Different indicators have varying color changes at different pH ranges, so using multiple indicators or pH meters provides a more precise measure of the pH of a solution.
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.

Why doesn't turps react with pH indicators?
most pH indicators are polar, whereas turps is non-polar so it doesnt mix well
What will change color in the presence of an acid or a base?
pH indicators change the color depending upon acidity or basicity.
