How indicators works?
pH indicators change their color according to the pH of a solution.
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 don't all acids turn indicators pink?
Not all acids turn indicators pink because the color change of an indicator depends on the pH of the acid. Different indicators have different color changes at different pH levels. Some indicators change color in acidic solutions, while others change in basic solutions.
What will change color in the presence of an acid or a base?
pH indicators change the color depending upon acidity or basicity.
What eles can you use for phenol red?
Other substances that can be used as pH indicators include bromothymol blue, methyl red, and litmus. These indicators change color at different pH levels, providing a visual indication of the acidity or alkalinity of a 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 compound changes color when used to determine the pH of a substance?
There are a variety of indicators used to determine change in pH. Different indicators change during certain ranges of pH. For example, phenolphthalein turns from clear to pink in a basic solution (approximately 7.8 to 9). There are universal indicators that cover the whole pH scale.
Examples of plant indicators for measuring pH values?
a plant pH indicator is onion
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 is the pH value of universal indicator?
When it is not mixed with any other solution, it is green. Green represents neutrality, so its pH is 7.
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.

Do acids have any effect on indicators?
Yes, acids can affect indicators by changing their color. Indicators are substances that change color in response to changes in pH levels, and an acid can cause this color change by altering the pH of the solution the indicator is in.
How do use solutions to find the colors of the indicators?
First, identify the indicators used in the experiment. Then, prepare a set of solutions with known colors at different pH levels. Finally, compare the color change of the indicators with the color changes in the solutions to determine the pH of the solution being tested.
