Indicators are substances that change color depending on the acidity or basicity of a solution. By adding an indicator to a solution of unknown pH and observing the color change, one can determine the approximate pH of the solution based on the color of the indicator at that pH range. This color change is due to the indicator's ability to undergo a reversible chemical reaction that is sensitive to changes in hydrogen ion concentration.

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.


Dyes with pH sensitive colors are used as?

pH indicators in chemistry to determine the acidity or basicity of a solution. These dyes change color depending on the pH of the solution, making them useful for identifying pH levels in experiments or quality control.


What do we call substances that change color depending on the pH the solution they are in?

Substances that change color depending on the pH of the solution they are in are called pH indicators. These indicators often undergo reversible color changes that are used to determine the acidity or alkalinity 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.


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.

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.

What can indicators identify?

Indicators are used frequently for testing pH; but many other indicators exist for other compounds or ions.


How do you use indicators to measure acidity and basicity?

Many different pH indicators exist, covering different ranges of acidity and alkalinity. Every pH indicator should come with its color guide to help determine the approximate pH level of whatever's being tested. The best way to determine the color's pH indication is a spectrometer.


What are common indicators are used to determine whether cargoes transported are acids or bases?

Common indicators used to determine whether cargoes are acids or bases include litmus paper (turns red in acids and blue in bases), pH paper (changes color based on the pH level), and universal indicator solution (changes colors to indicate the acidity or basicity of a substance). These indicators help in quickly identifying the nature of the cargo being transported.


How indicators works?

pH indicators change their color according to the pH of a solution.


What is an indicator and what are the common indicators used for pH?

An indicator is a substance that changes color in response to changes in pH levels. Common indicators used for pH testing include litmus paper (which turns red in acidic conditions and blue in basic conditions), phenolphthalein (which is colorless in acidic conditions and pink in basic conditions), and universal indicator solution (which changes color based on the pH of the solution).
