What does an universal indicator tell you about an acid that litmus doesn't?
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
How much does universal indicator cost?
The cost of universal indicator can vary depending on the brand, quantity, and supplier. On average, a small bottle of universal indicator can cost around $5-$10. Larger quantities or more specialized versions may be more expensive.
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 can't a litmus indicator be used to distinguish between solutions pH 2?
A litmus indicator cannot distinguish between solutions with the same pH, such as two solutions both at pH 2, because it only indicates whether a solution is acidic or basic, not the specific pH value. Since both solutions at pH 2 will turn litmus paper red, the indicator will not provide any additional information to differentiate between them. To differentiate between solutions with the same pH, more precise pH indicators or pH meters would be needed.
Why the universal indicator change colour when added 2 LiOH?
The universal indicator changes color when added to lithium hydroxide (LiOH) because LiOH is a strong base that dissociates in water to produce hydroxide ions (OH⁻). The presence of these hydroxide ions increases the pH of the solution, making it more alkaline. The universal indicator responds to this change in pH by shifting to a color that reflects the basicity of the solution, typically turning from green (neutral) to blue or purple (alkaline).
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.
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 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.
Why is a universal indicator more useful than litmus paper for measuring pH in some applications?
this is because it is more specific(Y):)

Why is a universal indicator better than a litmus?
coz universal indicator tells you whether its a strong or weak acid or alkali but litmus paper only tells you whether the sunstance is acid (red) or alkali (blue)
What effect does chlorine have on moist universal indicator?
Chlorine turns moist universal indicator paper red, then bleached. It has the same effect on blue litmus paper (red then bleached). this shows it is an acidic gas and so when reacts with sodium for example (an alkali metal) makes sodium chloride (salt).
A substance that directly determines the acidity or alkalinity of a fluid?
Use a universal indicator or litmus paper. Litmus paper will turn red in acidic conditions and blue in alkali conditions. Universal indicator can give a more accurate PH reading than litmus paper.
What is litmus solution?
yes it is
What is best universal indicator or litmus paper?
Universal indicators provide a broader range of pH values and can indicate the acidity or alkalinity of a solution with a color change across a spectrum, making them more versatile than litmus paper. Litmus paper, while useful for quickly identifying whether a solution is acidic or basic, only offers a binary result (red for acidic, blue for basic) without specific pH information. Therefore, for detailed pH analysis, universal indicators are generally considered better. However, for quick tests, litmus paper is convenient and effective.
