What is so special about universal indicator?
Universal indicator is special because it is a pH indicator that can change color over a wide range of pH levels (from acidic to basic). This makes it a versatile tool for quickly determining the pH of a solution by observing the color change, which can be useful in various experiments and applications.
Is shoe flower a natural indicator?
Yes, shoe flower (hibiscus) is a natural indicator due to the pigments present in its petals. The petals can change color based on the pH of the solution it is in, making it a useful tool for pH testing in certain applications.
What do you call a substance which is used to show changes in pH by its change in color?
An indicator. It is a substance that changes color in response to a change in pH, making it a useful tool in chemistry to visually determine the acidity or basicity of a solution.
How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
What is universal indicator?
It is a substance used to determine the strengths of acids and alkali.It changes color according to the pH of the material its in. It is so useful because the color also tells you how strong the substance is. As an example, if you were to put a few drops of the indicator in water it would go green. A few drops of it in cleaning products and it would go a deep purple.A universal indicator can give various colors to a huge variety of pH ranges.
Is plumbagin a natural indicator?
Yes, plumbagin is a natural indicator commonly found in plants like Plumbago and Drosera. It changes color based on the pH of the solution it is in, making it useful as a pH indicator in laboratory experiments.
Why is it difficult to measure the pH value of household bleach using universal indicator?
Household bleach is a strong base, typically with a pH of around 11-13, which is outside the color range of universal indicator, making it difficult to accurately measure its pH using this indicator. Universal indicator is more useful for measuring pH in the neutral to slightly acidic range. To accurately measure the pH of bleach, a pH meter or pH paper with a broader range would be more suitable.
Why is universal indicator often more useful than litmus indicator?
Universal indicator can show a wider range of pH levels compared to litmus indicator, which can only indicate acidic or basic solutions. Universal indicator provides a full spectrum of colors corresponding to different pH values, making it more precise and versatile for measuring pH levels in various solutions.

What name is given to an indicator which gives different odor in different medium?
This indicator is known as an olfactory indicator. It changes its smell based on the pH of the medium it is in, which can be useful for detecting changes in acidity or alkalinity.
What do you call a substance which is used to show changes in pH by its change in color?
An indicator. It is a substance that changes color in response to a change in pH, making it a useful tool in chemistry to visually determine the acidity or basicity of a solution.
How are universal indicator and the pH scale linked?
Universal indicator is a solution composed of several different indicators, each of which changes color at different pH levels. The pH scale is a way to measure the acidity or alkalinity of a substance based on its concentration of hydrogen ions. Universal indicator's color change corresponds to different pH levels, making it a useful tool for determining the pH of a substance.
What is the advantage of knowing the pKa of an acid-base indicator?
Knowing the pKa of an acid-base indicator allows us to determine the pH range over which the indicator changes color, making it useful for determining the endpoint of a titration. This information helps in selecting the appropriate indicator for a specific titration and ensures accurate results.
Why is a universal indicator more useful than litmus paper for measuring pH in some applications?
this is because it is more specific(Y):)
What component in some flowers makes a good pH indicator?
Anthocyanins are the components found in some flowers that act as a good pH indicator. They change color in response to changes in pH levels, making them useful for determining whether a solution is acidic or basic. Examples of flowers containing anthocyanins include hydrangeas and red cabbage.
A compound that can reversibly change color depending on conditions such as pH?
They are comonly known as "indicators" as the color change is useful for indicating what the pH of a solution is.
