I suppose that the preparation procedure is more difficult.
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.
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.
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.
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.
An indicator has to be able to change colors as the pH of the solution approaches ithe indicators pH range. For example, universal indicator starts out as a yellowish color in an acidic solution, then as it grows more neutral(more towords 7) it becomes a greener color, and as it grows more basic, it starts to become a blue color. Universal indicator will give you an indication of HOW acidic or alkaline a solution is, depending on the exact color. Litmus can only turn red or blue and can't distinguish between differing amounts of acid or base
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.
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.
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.
this is because it is more specific(Y):)

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)
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).
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.
yes it is

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.
