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.
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.
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.
What is universal pH paper?
Universal pH paper is a type of indicator paper that changes color based on the acidity or alkalinity of a solution. It covers a wide pH range and can be used to quickly determine the approximate pH of a liquid.
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 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 the difference between universal strips and narrow indicator strips?
Universal strips will show a wide range of pH values, but the color range between pH values is limited. The narrow strips will show a wider range of colors, but won't show you anything outside the range of the pH paper.
What is an advantage of using a universal indicator to test the pH compared to using litmus paper?
A universal indicator covers a broader pH range compared to litmus paper, which only gives a rough indication of acidity. Universal indicators provide a more accurate and detailed measurement of pH levels.
What is one limitation of universal indicator paper?
One limitation of universal indicator paper is that it may not provide a precise numerical pH value but rather a color change indicating a range of pH levels.
What colour is milk on a universal indicator?
Milk typically falls within a pH range of 6.4 to 6.8, which is slightly acidic. On a universal indicator scale, which uses a range of colors to indicate the pH of a substance, milk would likely appear as a shade of red or pink.
What is universal indicator very short answer only?
A universal indicator is a pH indicator that exhibits a gradual change in color to indicate the acidity or alkalinity of a solution. It can show a range of pH levels, typically from 0 to 14, with distinct colors corresponding to different pH values. Universal indicators are commonly used in laboratories and educational settings for pH testing.
What pH indicator should the scientists use?
Scientists should consider using universal pH indicator because it can provide a wide range of colors to indicate different pH levels.
