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 the pH indicator used in the citrate test?
Bromothymol blue is the pH indicator used in the citrate test. It turns blue at an alkaline pH, indicating that citrate has been utilized by the bacteria.
Why is universal indicator a valuable tool for measuring pH?
It is a simple and not expensive tool to measure pH.
Examples of plant indicators for measuring pH values?
a plant pH indicator is onion
Why is it difficult to measure pH value of household bleach using universal indicator?
Household bleach is a strong alkaline solution, making it difficult to accurately measure its pH using universal indicator. Universal indicator is more suited for measuring pH in the neutral to slightly acidic range, and may not provide an accurate or precise reading for highly alkaline substances like bleach. A pH meter or specific alkaline pH indicator may be more suitable for measuring the pH of household bleach.
Name the three most common ways of measuring pH?
The three most common ways of measuring pH are using pH meters, pH test strips, and pH indicator solutions. pH meters provide the most accurate and precise measurements, while pH test strips are convenient and easy to use. pH indicator solutions involve adding a few drops of a chemical that changes color based on the pH level of the solution.
What tool to use when measuring pH?
ph papers ++ More accurately, either pH papers with a colorimeter, or a pH meter that works on the conductivity of the fluid.
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 can measure pH?
pH can be measured using a pH meter, pH paper, or pH indicator solutions. These tools detect the acidity or basicity of a solution by measuring the concentration of hydrogen ions present.
What is the indicator use in potentiometric titration?
The indicator used in potentiometric titrations is typically a pH electrode. By measuring changes in pH during the titration process, the endpoint of the titration can be determined accurately. The pH electrode provides a continuous measurement of the solution's pH, allowing for a precise determination of the equivalence point.

What tool is best used to measure pH?
The most elementary one is Litmus Paper. It measures red for acid and blue for alkali. Then there is UNIVERSAL INDICATOR, a liquid, This will slowly change colour from red(very acidic (pH 1)) to green(neutrality) (pH 7) to indigo (Alkaline )PH14)) Theren there is a pH meter , which is an electronic probe put into the solution to read off the pH .
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.
