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.
Universal indicator is mostly preferred over litmus indicator why?
Universal indicator covers a wider pH range compared to litmus indicator, which only detects acidic or basic conditions. Universal indicator provides a more precise indication of the pH level of a solution by producing a range of colors across the pH scale.
What is universal indicator state the purpose for which this indicator is used?
Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.
Will strong acids turn universal indicator paper purple?
The pH scale ranges from 0-14. Universal indicator makes very acidic substances (with a pH of around 0) appear dark red, neutral ones green and very alkaline ones dark blue.
Why is universal indicator the best indicator the best indicator for jasmine to use in an experiment?
Universal indicator is the best choice because it can indicate a broad range of pH values accurately, from acidic to alkaline solutions. This makes it suitable for a wide range of experiments involving pH variations. Additionally, universal indicator changes color based on the specific pH of the solution, allowing for easy and precise determination of the solution's acidity or alkalinity.
Is bleach a universal indicator?
No, bleach is not a universal indicator. Universal indicators are mixtures of dyes that change color across a range of pH values, while bleach is a strong oxidizing agent commonly used for disinfection and cleaning purposes.
What is the name of the indicator that gives you the range of colours for different pH numbers?
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.

What colour does universal indicator change to if carbonate acid is added?
Universal indicator changes to a color in the green/blue range when carbonate acid is added. This indicates a basic or alkaline pH level.
Is the universal indicator or phenolphthalein is more accurate?
Universal indicator is generally considered more accurate than phenolphthalein because it provides a broader range of colors to indicate the pH of a solution across a wider pH range. Phenolphthalein is more limited in its pH range and color changes.
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.
What is the specific name of universal indicator?
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.
Why does the typical base indicator exhibit its color change over a range of about 2 PH units?
The usual range of the color change on the indicator is between 1.5-2 pH units because of the sensitivity of the indicators. The universal indicator is used in most test.
